POET’s DenseLight launches digitally control integrated light module for wind LiDAR

POET Technologies Inc of Toronto, Canada and San Jose, CA, USA — a designer and manufacturer of optoelectronic devices, including light sources, passive waveguides and photonic integrated circuits (PIC) for the sensing and datacom markets — and its Singapore-based subsidiary DenseLight Semiconductor have announced that samples of its new Integrated Light Module (ILM), designed for high-performance wind light detection & ranging (LiDAR) and other environmentally stressed applications, will be available to customers in April in limited quantities.

Because of expected high customer demand, the DL-BF9D will be on allocation beginning immediately. Company representatives are taking initial sample orders in booth 4085 at the SPIE Photonics West 2019 exhibition in San Francisco (5–7 February), where DenseLight is exhibiting its suite of standard components for datacoms and sensing applications. In particular, for customers with an immediate requirement, the firm is offering quantities of its DL-DFB9C ILM, which offers the same enhanced performance but with analog control at a more affordable price.

The new DL-BF9D digital version has enhanced features and is a member of the Constellation series of ILMs, offering lower relative intensity noise (RIN) and phase-noise performance as well as improved linewidth stability performance compared with similar modules from other suppliers, it is claimed.

Key features include: tunable optical power; an operating temperature (chassis) of 0-50°C; RIN <-150dB/Hz (<-160dB/Hz 10-50MHz); low phase noise; linewidth, typical 10kHz; mode-hop-free operation over temperature; side-mode suppression ratio (SMSR) >45dB; and digital control interface via USB.

The DL-BF9D ILM is suitable for a wide range of communications and sensing applications where noise performance and linewidth stability are critical, such as wind LiDAR and other distributed acoustic sensing (DAS) applications.
