POET Demonstrates Superior Resonant Cavity Detector Performance

Process transfer to 6-inch production fab successfully validated on multiple runs

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.

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.
