Demonstration Of Endless Phase Modulation For Arbitrary Waveform Generation

, 2005
We have developed a novel modulation scheme for shifting the frequency of an optical beat signal by improving a conventional serrodyne system via time division multiplexing.

Ultra-high spur-free dynamic range RF synthesis using optical homodyne serrodyne technique

, 2007
It is reported that the spur-free dynamic range (SFDR) of an optically hornodyned serrodyne signal depends on the relative phase difference between the beating optical waves. By optimising this parameter, a I MHz tone with 63 dB SFDR has been synthesised,

Resonator Fiber Optic Gyro with Bipolar Digital Serrodyne Scheme Using a Field-Programmable Gate Array-Based Digital Processor

, 2011
A field-programmable gate array-based digital processor is proposed and demonstrated experimentally for a resonator fiber optic gyro (R-FOG) with a bipolar digital serrodyne phase modulation scheme, which we previously proposed especially for R-FOG ...

Zeptosecond‐Scale Single‐Photon Gyroscope

Advanced Quantum Technologies, Volume 7, Issue 9, September 2024.
A novel approach coupling Sagnac interferometry with estimation theory is proposed, presenting a fully fibre‐based sensor that employs a quadrupole winding‐fibre optic gyroscope together with serrodyne modulation and nanowire detectors to achieve an unparalleled photon delay detection limit of 26 zeptoseconds.

Near-Capacity Irregular Bit-Interleaved Coded Modulation [PDF]

, 2008
An Irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregularity of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and the bit-to-symbol
