POET Technologies’ DenseLight Subsidiary Expands Industry-Leading Narrow Linewidth Laser Solutions for Test and Measurement Applications
GlobeNewswire•January 31, 2017

SAN JOSE, Calif., Jan. 31, 2017 (GLOBE NEWSWIRE) -- POET Technologies Inc. (“POET”) (POETF) (TSX Venture:PTK), a developer of opto-electronic fabrication processes for the semiconductor industry, today announced its wholly-owned subsidiary, DenseLight Semiconductors, an innovator of high performance lasing solutions for optical sensing applications, unveiled its next generation Constellation Series of Narrow Linewidth Laser (NLWL) solutions for test and measurement applications. Introduced specifically to meet superior Relative Intensity Noise (RIN) performance and ultra-narrow linewidths requirements, this new family of products simplifies the overall design process for OEMs, while shortening development time and significantly accelerating time-to-market.

The Constellation Series of NLWL lasers was specifically designed to provide low noise capability with narrow linewidths, increasingly a requirement for a range of optical sensing solutions across a number of end market applications. DenseLight’s new Constellation Series integrated light modules [CBF Series] offers narrow spectral linewidths (e.g., 10, 5 and 1 Khz), excellent Side-Mode Suppression Ratio (SMSR), power stability and a very high wavelength stable laser output. These feature sets are ideally suited for a wide range of high precision remote sensing system applications, including wind-farm LIDAR; meteorological atmospheric LIDAR; Distributed Acoustic Sensing (DAS); Perimeter Intrusion Detection Systems (PIDS); distributed strain and temperature sensing using Brillouin Optical Time Domain Reflectometry (BOTDR); precision optical metrology & instrumentation; and high resolution optical gas & chemical sensing.

Senior Vice President of Sales and Marketing at DenseLight, Bryan Patmon, commented, “Our newest family of laser products delivers the most reliable laser performance with the lowest noise output. We are greatly simplifying the process for customers to create and implement integrated systems and solutions with advanced capabilities.”

DenseLight’s first Constellation Series product, the CBF-9, is complete with a proprietary specialty laser module fixed into a newly designed hermetically-sealed Butterfly package, as well as an integrated laser driver and temperature controller. Premiering with a C-band laser, the CBF series of products will eventually be extended across a wide wavelength range, inclusive of the O, E, S, C and L bands. The new CBF platform can be customized for multiple use and application options to meet customers’ specific requirements.

A list of the Constellation Series features and specifications can be accessed on POET Technologies website at http://www.poet-technologies.com/constellation-series/.

Engineering samples are expected to be available beginning in the second quarter of 2017, with production commencing in the second half of 2017.

A New Family of Derivative Gain Chips
DenseLight also expands its product portfolio of gain chips, based on proprietary InP active waveguide designs to provide high optical gain over a broad wavelength range and near-circular optical far-field profile. Gain chips are typically integrated in external cavity laser systems as the laser gain source. The gain chip is delivered as chip or chip-on-submount, with high reflectivity (HR) coating on the back facet and low reflectivity anti-reflecting (AR) coating on the angled front facet. The DenseLight gain chip family will feature very stable operational characteristics as well as superior tuning capabilities. The gain chip product portfolio will offer ASE optical peak wavelength coverage from 1260nm to 1650nm.

DenseLight’s expanding portfolio of optical sensing solutions will be demonstrated at the Photonics West 2017 conference in San Francisco, California from January 31 to February 2, 2017.
