FSR estimates depend on effective index and diameter; different modes have different effective indices. Application value comes from high Q, narrow resonances, strong enhancement, and sensitive responses to environmental disturbances. Uses include ultranarrow lasers, microcavity nonlinear optics, photoacoustics, physical sensing, biochemical detection, ultrastable frequency references, and optical gyroscopes. JCOPTIX supplies cavities plus packaging/coupling, stability management, thermal tuning, and interface customization. They lower research barriers to high-Q devices and provide instrument/industrial teams an expandable path from components to modules. For precision metrology, communications, biomedicine, and quantum sensing, ultrahigh-Q cavities link basic research and engineering; application-specific customization is available. Thermal compensation improves stability and overcomes frequency drift as stated. Ultrahigh Q/stability, narrow modes, and small size facilitate integration for gyroscopes, particle/acoustic sensors, light-matter studies, and ultrasensitive broadband ultrasound. Before delivery, national-/industry-standard procedures test temperature/humidity, salt spray, vibration, acceleration, drops, failure analysis, and aging, with good performance reported. Devices ship packaged or unpackaged. Packaging extends life, limits Q degradation, adds functions, and isolates thermal/vibration disturbances. Resonant-mode distribution and typical linewidth: FSR≈c/(n_g*L). The source defines cc as vacuum light speed, n_g as frequency-dependent group index, and L as optical-path length. For custom spherical cavities the geometric circumference is 2π*R. FSR is a fixed frequency interval determining sparse/dense modal distribution: larger FSR separates modes more, smaller FSR packs them closer. Geometry dominates; smaller cavities generally have larger FSR. Resolving modes also depends on linewidth Δν, normally FWHM, with Q=ν/Δν. Q measures storage ability and total absorption/scattering/radiation loss; high Q and suitable FSR jointly determine spectra. Crystal characteristics include low absorption/scattering, controllable index dispersion, anisotropy, and thermal stability. Precision crystal cavities can have higher Q than conventional silicon devices and more consistent mode spacing than amorphous cavities. JCOPTIX illustrates mode distributions for 1. fused silica, 2. MgF₂, 3. CaF₂.

Fiber Optomechanics
Shconnet
Selectable Operating Wavelength Range: 180-2000nm Coupling Efficiency [Single-Mode Fiber]: >60% Coupling Efficiency [Multimode Fiber]: >80%
Pigtailed laser-to-fiber couplers are recommended for permanent or semipermanent coupling without frequent fiber changes, high coupling efficiency and stable output, low back-reflection and high polarization-maintaining capability. The fiber and focusing lens are permanently joined with adhesive, then placed in a tilt-adjustable flange positioned by two screws. Neither fiber nor lens can be exchanged. LPSC-01 is a contact type with the internal fiber end face touching the lens; LPSC-03 is noncontact with a gap. Typical back-reflection of the contact type is -25dB. Angled polishing of the internal fiber end reduces reflection in noncontact versions, available with -40dB or -60dB back-reflection.

Fiber Clamps and Accessories FAH-AP Fiber Optomechanics Jcoptix
Body Material: SUS303 Surface Treatment: PVD Coating Quantity: 1
JCOPTIX multiaxis fiber-coupling accessories include rotators, clamps, and magnetic hold-downs for bare fibers. Special surface treatment makes clamps soft and oxidation-resistant. Soft materials at magnetic clamp contact points protect fibers while holding them stably. Hold-down fiber clamp. Model: FAH-V1. Fiber diameter Ø125-341 μm; fits DMF-R6/DMF-L6 six-axis coupling stages; FAH-AP adapts it to five-axis stages. Ordinary clamps may not support fiber tips close enough to small-waveguide input ports. JCOPTIX FAH-V1 has a tapered tip for visual observation of the fiber/waveguide interface. Two supplied FAH-V1M magnetic hold-downs secure the fiber and are also sold separately. Two M3 screws and a key are included. Quick-release fiber clamp. Model: FAH-V2. Diameter Ø125-341 μm; for DMF-R5S/DMF-L5S five-axis coupling stages. JCOPTIX FAH-V2 attaches fibers to DMF-L5S/DMF-R5S stages for alignment. It gently holds fibers in a precision V-groove. A lower V-groove matches the five-axis stage and locks with a side screw. A bottom 1 M4 hole also mounts directly to posts. Threaded-hole fiber clamp. Model: FAH-V3. Bottom M4 thread; V-groove for Ø110-341 μm fibers; thumbscrew adjusts magnetic force. Simple mechanics clamp the external buffer without damaging the fiber. A thumbscrew adjusts magnetic attraction. The bottom M4 hole attaches Ø12.7 mm posts or integrates into breadboard/table assemblies. Fiber-clamp adapter plate. Model: FAH-AP. Direct five-axis-stage mounting; side set-screw locking; dovetail adapts FAH-V1. This JCOPTIX plate mounts FAH-V1 on DMF-L5S/DMF-R5S five-axis coupling stages. A bottom dovetail secures to the stage; a top rectangular guide block mates with FAH-V1's bottom rectangular groove for precise, reliable, convenient location. Magnetic hold-downs for FAH-V1. Model: FAH-V1M-P6. 6 per pack; soft undersides protect bare fibers; use with FAH-V1. These JCOPTIX hold-downs work with FAH-V1 clamps. Appropriate magnetic force secures bare fibers on FAH-V1 without damage, and soft bottom material adds protection. FAH-V1 magnetic hold-downs replace those supplied with FAH-V1 or support other custom fiber assemblies. Fiber rotator. Model: FSS-FR007. Mounts on compact three-axis stages; reliable V-groove location; accepts bare uncoated fiber with 125 µm cladding; magnetic pressure plate with screw-adjustable force; continuous 360-degree rotation lockable anywhere; maximum eccentricity 10μm. This JCOPTIX rotator suits angle-sensitive systems such as polarization experiments/coupling. A platform V-groove coarsely locates bare fiber, secured by a pressure plate. Its upper screw adjusts force to avoid stress deformation and induced birefringence. Mounted bare fiber rotates 360°, locks anywhere, and has maximum eccentricity 10μm. The opposite-end knob has 5° graduations; with an approximately 3° indicator-line width it provides about 2° minimum resolution. A locking screw secures the core's angular position. A 3 mm-wide base key fits compact-stage products and can be used with other fiber clamps/accessories. Compact-stage tops have central keyways for precise accessory alignment along the stage axis. Note: the precision rotator is preset for 125 µm outside-cladding-diameter fibers with buffer stripped. Coating, also called buffer, protects glass cladding from particles that could cause breakage. Some specialty coatings also act optically as a second cladding; consider optical properties before removal.
