POET Technologies’ DenseLight Subsidiary Announces Sampling of Avalanche Photodiodes and PIN Photodiodes for the 10G Datacom & Telecom Markets

September 6th, 2017

Detector portfolio to include Monitor Photodiodes and Photodiode arraysfor 100G Datacom Applications

SAN JOSE, CA, September 6, 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 its wholly-owned subsidiary, DenseLight Semiconductors, an innovator of high performance lasing solutions for optical sensing applications, has begun sampling Avalanche Photodiodes (APD) and PIN Photodiodes (PIN) for the 10G Datacom and Telecom markets. In addition, DenseLight has also begun sampling its Monitor Photodiode (MPD) arrays for applications in 100G Datacom applications. The MPD arrays are available in a 1x4 configuration for Quad Channel applications with customizable pitches.

The APD and PIN products are targeted at the GPON FTTx markets, specifically Optical Line Terminal (OLT) and Optical Network Unit (ONU) devices. DenseLight’s solutions are expected to provide a cost competitive alternative to current offerings, while meeting the performance needs of customers deploying systems in these markets.

The APD and the PIN are top illuminated mesa InGaAs-based chips. The APD has a 30um aperture, and the PIN has a 40um aperture. Both are available in a three pad (G-S-G) option and a dual pad version. These devices have been optimized for 10Gb/s applications.

Key features:


  • High bandwidth APDs
  • Dark Current < 5nA
  • Operating temperature range of -40C to 85C
  • Responsivity 0.9W/A @ 1310nm & 1550nm
  • Sensitivity ~ -31dBm @ BER of 10-12


  • High bandwidth PINs
  • Dark Current < 5nA
  • Operating temperature range of -40C to 85C
  • Responsivity 0.9W/A @ 1310nm & 1550nm

DenseLight Semiconductors is exhibiting its suite of standard components for Data Communications and Sensing applications, along with 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.
