Excess Loss in Homodyne Detection Originating from Distributed Photocarrier Generation in Photodiodes
Takahiro Serikawa, Akira Furusawa
The distributed absorption of photons in photodiodes induces an excess noise in continuous-wave photodetection above the transit-time roll-off frequency. We show that it can be tre…
Schrödinger's cat in an optical sideband
Takahiro Serikawa, Jun-ichi Yoshikawa, Shuntaro Takeda +4
We propose a method to subtract a photon from a double sideband mode of continuous-wave light. The central idea is to use phase modulation as a frequency sideband beamsplitter in t…
500MHz resonant photodetector for high-quantum-effciency, low-noise homodyne measurement
Takahiro Serikawa, Akira Furusawa
We design and demonstrate a resonant-type differential photodetector for low-noise quantum homodyne measurement at 500MHz optical sideband with 17MHz of bandwidth. By using a micro…
