Integrated photonic transceivers at sub-terahertz wave range for ultra-wideband wireless communications


FP7 ICT-5-3.9 Microsystems and Smart Miniaturised Systems


This project is supported by the European Commission under the Information and Communication Technologies (ICT) Theme of the 7th Framework Programme, within the Smart micro/nano systems area of ICT Challenge 3: Components, Systems, engineering.

Public Year 1 Summary

WP2 (Dual Wavelength Signal Source)
Active/Passive photonic integration is the key to incorporate functionality in the optical domain. Two integrated dual wavelength signal sources (iDWSS) device types are foreseen in the project.

AWG
Arrayed waveguide grating (AWG) based devices are foreseen in the project, where the wavelength selection function of the AWG is the key element to define the wavelength separation of the two optical signals for optical heterodyning.

WP3 (High Speed Photodiode)
70 GHz photodiode
During the first year, 70 GHz photodiodes have been optimized, fabricated and delivered for submounting. Simulation results show an optimized optical coupling efficiency of about 80% at the fiber/POW-interface and about 95% from the passive to the active waveguide. The electrical output of the photodiode appears as a grounded CPW output transmission line. The PD is showing a flat frequency response (±1.5 dB) over the entire E-band (60 to 90 GHz).

 

 

WP4 (Sub-system Integration and Packaging)
Schottky Receiver
During the first year, for the Schottky diode receiver, within the iPHOS project a low video-resistance and high responsivity diode has been developed. According to the specification to mount the device on the receiver antenna, a substrate-less diode structure with small geometry was designed.

The frequency range of this device covers from 50GHz up to beyond 1THz, which is suitable for both iPHOS target carrier frequencies.
