Directly modulated laser 10G DML Emcore or Agere 1861 Series 1310nm 1861D
The 1861 directly-modulated laser (DML) is a cost-effective solution for 10 Gb/s digital transmission of up to 60 km using traditional intra-city SMF-28™ single-mode fiber links. The 1310 nm wavelength eliminates the concern about dispersion control over most installed intra-city fiber plants. The package contains a high-speed DFB laser chip, thermoelectric cooler, thermistor, optical isolator, and a rear-facet monitor photodiode for external optical power control.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.
Medical disposable‑device manufacturers have long demanded high‑performance interconnect accessories for single‑use equipment. The newly‑launched REDEL‑P disposable‑connector family addresses this requirement and delivers premium‑grade electrical connections for varied one‑time‑use medical instruments.
On January 21, 2026, SPIE Photonics West, one of the world’s leading photonics events, was held in San Francisco, USA. RaySea presented its latest self‑developed VCSEL achievements at this prestigious exhibition. Dr. Lai, the company’s senior R&D representative, delivered a technical speech during the dedicated VCSEL session. His presentation covered cutting‑edge progress of in‑house multi‑junction VCSEL solutions built for automotive lidar and embodied‑intelligence robots, drawing strong attention from the global photonics community.
