POET Technologies’ DenseLight Subsidiary Announces New Family of External Cavity Narrow Linewidth Lasers

September 7th, 2017

New “Constellation Series” provides enhanced performance, lower Relative Intensity Noise (RIN) and industry leading external cavity wavelength tuning capability

SAN JOSE, CA, September 7, 2017 – POET Technologies Inc. (“POET”) (OTCQX: POETF; TSX Venture: PTK), a designer, developer and manufacturer of optoelectronic devices, including light sources, passive wave guides and Photonic Integrated Circuits (PIC) for the data communication and telecom markets, today announced that its wholly-owned subsidiary, DenseLight Semiconductors, an innovator of high performance lasing solutions for optical sensing applications, has introduced a new family of its specialized external cavity narrow linewidth (NLW) laser products with enhanced capabilities. These new NLW lasers are assembled in integrated laser modules (ILM) and provide feature rich extensions to the existing BF series ILMs. The new family will feature laser sources with lower Relative Intensity Noise (RIN) relative to current offerings and at the low-end include a standard CW capable light source (BF9C). A higher-end module will add power tuning capability, lower RIN and improved temperature range (BF15); the flagship product will offer highly integrated BF18 with even lower RIN and “super wide” tunability.

Rajan Rajgopal, President and General Manager of DenseLight Semiconductors, stated, “Our new designs are highly scalable, and the inherent hybrid design feature is a new element to the BF18, which offers tunability ranges not yet seen or realized by conventional NLW-ECL lasers today. DenseLight’s new NLW capabilities and products will be the cornerstone of our ability to deliver compelling solutions that are well suited for real-life sensing environments.”

The performance features of this new family of Integrated Laser Modules are outlined below.

Product Model RIN
Wavelength Tunability
Tunable Optical Power Operating Case Temperature
(deg C)
Modulation Capability
BF9C 150 n/a Yes 0 to 60 No




0 to 70

BF18 160 > 300 Yes 0 to 60 Yes

The new family provides superior value with the key features of lower RIN (< - 150 dB/Hz), narrow linewidth (<6 Khz), and now “super wide” wavelength tunability > 300 picometer (pm) in its flagship BF18 ILM.

DenseLight’s BF18 product compares favorability to alternative fiber laser sources, offering improved RIN performance, an excellent side mode suppression ratio (SMSR), and a wide tuning range, which is believed to exceed any conventional external cavity based laser available today. The Company believes this new laser will be the foundation for addressing the rapidly growing need for tunability and noise performance in the future.

These new product introductions primarily target a wide range of communication and sensing applications, including coherent communication, laser interferometry, LIDAR wind detection, long distance fiber, fiber array sensing and acoustic sensing.

DenseLight Semiconductors is exhibiting its suite of standard components for Data Communications and Sensing applications, as well as its 100G compatible CWDM and LAN WDM multiplexing solutions, at the China International Optoelectronic Expo (CIOE) (Hall 6, Booth 6001/6002) on September 6-9, 2017.
