An Arbitrary Biased EOM-based Pulse-Picker with Programmable Repetition Rate using FPGA
Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), IEEE Xplore,
•
2023
Abstract: We experimentally demonstrate an arbitrarily biased electro-optic Mach-Zehnder modulator-based pulse picker with variable repetition rate (from 50 MHz to 500kHz) by using a fast synchronized FPGA. We report a maximum pulse extinction ratio of 34 dB.
Device dependent distortion correction in time-stretch photonic analog to digital converters using deep neural networks
Optical Fiber Communication Conference, Technical Digest Series (Optica Publishing Group, )
•
2024
Abstract: We experimentally demonstrate a novel deep learning-aided time-stretch photonic front end architecture to overcome device-dependent distortions to improve the signal-to-noise and distortion ratio by more than 24 dB, and reduce the bandwidth requirements of the back-end electronic ADC by three times.
A Dither Free Automatic Bias Controller for Multichannel Optical Upconversion Systems
IEEE Opto-Electronics and Communications Conference (OECC), 2024 IEEE Xplore,
•
2025
Abstract: In this work, we demonstrate a dither-free automatic bias controller for dense wavelength division multiplexing-based multichannel analog radio over fiber systems. The analog optical transport is implemented as an optical doubling scheme using a two-stage external modulation setup, emulating a mmWave 5G fronthaul scenario.
Adaptive Polarization Alignment for Polarization-Independent Gain in OPAs Using SPGD
IEEE Photonics Conference (IPC), Singapore, IEEE Xplore,
•
2025
Abstract: We present an automatic polarization aligner using the SPGD algorithm to achieve polarization-independent gain in an optical parametric amplifier (OPA). The polarization state of the input pump is adjusted automatically and a gain error of < 0.07 dB between orthogonal signals is achieved within 25 seconds.
