Extending the PZT bandwidth of an optical interferometer by suppressing resonance using a high dimensional IIR filter implemented on an FPGA
Masanori Okada, Takahiro Serikawa, James Dannatt +4
This paper considers the application of FPGA-based IIR filtering to increase the usable bandwidth of a piezoelectric transducer used in optical phase locking. We experimentally per…

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…
