POET demonstrates superior resonant cavity detector performance
POET Technologies, a developer of opto-electronic fabrication processes, has reported superior responsivity parameters on the first sets of 6 inch production wafers for its integrated resonant cavity detector.
This is a key milestone in successfully validating POET's technology transfer to its high volume production foundry supplier, according to the company.
The POET (Planar Opto Electronic Technology) platform is a patented semiconductor fabrication process that uses GaAs technology to combine electronic and optical elements on a single integrated circuit.
At a bias voltage of 3.3V, POET detectors have demonstrated a room temperature thyristor enhanced saturated responsivity of 13A/W at an input optical power threshold of less than 200mW and at an aperture of 10mm. This is about 20 times higher on a three times smaller device relative to typical 850nm PiN diodes.
Prototypes of the detector, which will be the company's first product, are scheduled for the end of 2016.
Multiple 6-inch wafer lots of VCSELs and transistors were also processed at the foundry. Testing and characterisation of these devices is underway and POET expects to require further development cycles through additional wafer processing to fully achieve the true potential for these integrated opto-electronic devices.
"We are very excited with both the device results so far and the validation of our process transfer to scalable production environment," said Subhash Deshmukh, chief operating officer of POET Technologies. "Over the next few months we plan to make additional announcements on our key milestones and device performance as we continue our aggressive drive towards commercialisation of POET's highly differentiated technology."
POET's chief scientist Geoff Taylor will be retiring effective April 30, 2016, in order to focus on recuperation from multiple knee replacement surgeries.
"The company is now on the verge of successful growth under its new leadership and I believe is well positioned to produce critical prototypes necessary for POET to be recognised as a leader in the data communications market," said Taylor.
