We describe an experimental demonstration of fiber-based optical phase-sensitive amplification for improved detection of correlated single-photon pairs. A measured coincidence gain of 4.5dB provides 3dB improvement in the detection system signal-to-noise ratio.
This talk will discuss opportunities for photonics to contribute to signal processing applications in general, and RF signal processing in particular. Key issues associated with embedded photonic links, important analog RF functions, and key component and systems requirements will be addressed. Progress in silicon photonics and associated systems technologies, along with basic proof of concept demonstrations...
We demonstrate a wavelength-tunable optical channelizing filter with a high extinction ratio (50 dB), a narrow bandwidth (2.4 GHz), and a large free spectral range (50 GHz) using high-order coupled silicon rings.
We demonstrate the first reconfigurable, cascadable silicon photonics unit cell fabricated in commercial wafer-scale processes using a single 500 ps delay line and allowing independent FIR and IIR response for high-resolution RF filtering and correlation applications.
