In this work, a new concept of photonic noise source has been developed and characterized, based on Germanium-on-Silicon high speed photodiode (GeHSPD). This photodiode RF output power has been preliminary characterized up to 210 GHz, using a dedicated optoelectronic bench and demonstrating available power in the range of −30 dBm. Its noise output power has been then measured using a noise receiver...
A new Optical-High-Frequency test structure and dedicated test bench have been developed to characterize a Germanium-on-Silicon photodiode intended to be used as an integrated noise source, a first step to high frequency transistor noise figure on-wafer extraction. Continuous wave signals have been measured from these 1550 nm photodiodes, with RF power higher than −20 dBm at 109 GHz.
