Bias-Free Silicon-Based Optical Single-Sideband Modulator Without 2nd-Order Sideband

open access: yesIEEE Photonics Journal, 2020
In this paper, a bias-free silicon optical single-sideband (OSSB) modulator without 2nd-order sideband is proposed and theoretically investigated. The proposed modulator is based on a dual-drive Mach-Zehnder modulator (DDMZM) and silicon photonics ...

Bandwidth of linearized electrooptic modulators [PDF]

open access: yes, 1998
Many schemes have been proposed to make high dynamic range analog radio frequency (RF) photonic links by linearizing the transfer function of the link's modulator. This paper studies the degrading effects of finite transit time and optical and electrical
