Ultrafast dual-drifting layer uni-traveling carrier photodiode with high saturation current

High-power high-linearity flip-chip bonded modified uni-traveling carrier photodiode.

We demonstrate a flip-chip bonded modified uni-traveling carrier (MUTC) photodiode with an RF output power of 0.75 W (28.8 dBm) at 15 GHz and OIP3 as high as 59 dBm. The photodiode has a responsivity of 0.7 A/W, 3-dB bandwidth > 15 GHz, and saturation photocurrent > 180 mA at 11 V reverse bias.

An Optoelectronic Clock Recovery Circuit Using a Resonant Tunneling Diode and a Uni-Traveling-Carrier Photodiode∗

A clock recovery circuit is a key component in optical communication systems. In this paper, an optoelectronic clock recovery circuit is reported that monolithically integrates a resonant tunneling diode (RTD) and a uni-traveling-carrier photodiode (UTC-PD). The circuit is an injection-locked-type RTD oscillator that uses the photo-current generated by the UTC-PD. Fundamental and sub-harmonic c...

ALMA MEMO 399 Millimeter Wave Generation Using a Uni-Traveling-Carrier Photodiode

We have designed a new photomixer using a uni-traveling carrier photodiode (UTCPD) for generation of W-band radiation. The UTC-PD is integrated on a InP chip with DC and RF circuits and the chip is mounted upside down on a fused quartz substrate which is placed in a microstrip channel across a quarter-height W-band waveguide. A simple crossshaped microstrip-waveguide transition printed on the q...

5 Gbps wireless transmission link with an optically pumped uni-traveling carrier photodiode mixer at the receiver.

We report the first demonstration of a uni-traveling carrier photodiode (UTC-PD) used as a 5 Gbps wireless receiver. In this experiment, a 35.1 GHz carrier was electrically modulated with 5 Gbps non-return with zero on-off keying (NRZ-OOK) data and transmitted wirelessly over a distance of 1.3 m. At the receiver, a UTC-PD was used as an optically pumped mixer (OPM) to down-convert the received ...
