POET TECHNOLOGIES DENSELIGHT SUBSIDIARY INTRODUCES HIGH-POWER 1310NM DISTRIBUTED FEEDBACK (DFB) LASERS FOR 100G SILICON PHOTONICS APPLICATIONS

Poet Technologies Inc.'s wholly owned subsidiary, DenseLight Semiconductors, will start sampling high-power, continuous-wave, 1,310-nanometre, distributed-feedback (DFB) lasers for 100G silicon photonics applications early in the fourth quarter of 2017. Also within this time frame, DenseLight will begin sampling long wavelength 1650nm DFB lasers for the Test and Measurement, Optical Time Domain Reflectometry (OTDR) and Photonics/Biomedical sensing markets. This series of DFB lasers are based on DenseLight's proprietary Indium Phosphide (InP) Multiple Quantum Well (MQW) technology, manufactured in the Company's cleanroom facility in Singapore. These DFB lasers are the latest addition to the product portfolio, which currently consists of Super Luminescent LEDs (SLEDs), Gain Chips, narrow nine width Fiber Bragg Grating (FBG) lasers and Integrated Light modules.

With the ever-growing demand for more bandwidth, data center operators are actively deploying low-cost, scalable, single mode optics-based 100G transceiver solutions. Furthermore, the growing demand for bandwidth is driving the need for companies to deploy Test & Measurement systems that monitor the quality of networks. In response to increasing customer requests, DenseLight has added a range of uncooled DFB lasers to its product portfolio starting with high-power 1310nm lasers for Silicon Photonics applications and 1650nm lasers for Test and Measurement applications. DenseLight will introduce these lasers in either chip form or in multiple packaged configurations, offering optimum performance in a range of demanding applications, including Data Communications, OTDR, Distributed Acoustic Sensing (DAS) and Spectroscopy (chemical and gas) detection.

The initial samples are expected to be at 1310nm and 1650nm, followed by 1625nm. Other standard wavelength ranges between 1270nm and 1670nm are expected to be available soon thereafter.

The high-power continuous wave 1310nm DFBs are expected to generate peak power levels of 60mW across temperature, which is required for today's 100G Silicon Photonics applications.

The key features of the other DFB products:

• Uncooled
• Operating temperature from -5C to 70C
• Optical Output from min 3mW
• Slope efficiency of typical 0.20mW/mA @ 25C
• Available in TO-56 Aspherical Lens, TO Pigtail & 14 Pin Butterfly package

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.
