POET To Introduce Lasers For 100G Silicon Photonics


Denslight subsidiary ready to sample 1310nm and 1650nm InP DFB lasers early in Q4

POET Technologies, a US developer of optoelectronic devices for data communications and telecoms, has announced that its subsidiary, DenseLight Semiconductors, will start sampling high-power, continuous wave 1310nm Distributed Feedback (DFB) lasers for 100G silicon photonics applications early in Q4 2017.

Also within this time frame, DenseLight will begin sampling long wavelength 1650nm DFB lasers for test and measurement, optical time domain teflectometry (OTDR) and photonics/biomedical sensing.

This series of DFB lasers are based on DenseLight's proprietary InP Multiple Quantum Well (MQW) technology, manufactured in the company's cleanroom facility in Singapore. They are the latest addition to the product portfolio, which currently consists of Super Luminescent LEDs (SLEDs), Gain Chips, narrow nine width Fibre Bragg Grating (FBG) lasers and Integrated Light modules.

With the ever-growing demand for more bandwidth, datacentre 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.

New board appointment

POET has also announced the appointment of Jean-Louis Malinge to its board of directors. Concurrently, Ajit Manocha, who served on the board since July 2014, has resigned to devote his time to his new position as president and CEO of SEMI, a global industry organissation, while remaining engaged with POET as a strategic advisor.

Jean-Louis currently serves as partner with ARCH Venture Partners, an early-stage venture capital firm with nearly $2 billion under management. Additionally, he also serves as a managing director for YADAIS, a consulting firm in the photonics and telecommunications industries, and is a board member of EGIDE SA, which designs, manufactures and sells hermetic packages for the protection and interconnection of several types of electronic and photonic chips.

Prior to his consulting and venture capital engagements, Jean-Louis served as the CEO of Kotura, a silicon photonics company that designed and manufactured CMOS optical components, until he sold the company in 2013 for $82 million to Mellanox. Previous to Kotura, he worked for more than 15 years at Corning, an optical, display and advanced materials technologies firm, where he held various executive positions including vice president of optical networking components.

Jean-Louis Malinge holds a Masters Degree in Physics from Institut National des Sciences Appliquées in Rennes, France along with an Executive MBA from the MIT Sloan School in Boston.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
