Abstract

ABSTRACT A frequency-doubled microwave photonic phase shifter (MPPS) without optical filter is proposed. The MPPS is based on an integrated dual-polarization dual-parallel Mach-Zehnder modulator (DP-DPMZM) and a polarization modulator (PolM). The DP-DPMZM with a 90° polarization rotator in one arm is used to generate an optical carrier suppressed double sideband (OCS-DSB) signal with orthogonal polarization, and the PolM with two modes opposite phase modulation is used to introduce the optical phase shift between the two orthogonally polarized tones. Simulations show that the MPPS can realize a continuously tunable phase shift of 360° with only one DC bias voltage, and is not sensitive to the optical carrier wavelength and microwave signal frequency since no optical filter is used.

基于集成双偏振双平行马赫-曾德尔调制器的微波光子移相器

提出了一种无滤光片的倍频微波光子移相器(MPPS)。MPPS基于集成双偏振双并行马赫-曾德尔调制器(DP-DPMZM)和偏振调制器(PolM)。采用单臂90°偏振旋转器的DP-DPMZM产生具有正交偏振的光载波抑制双边带(OCS-DSB)信号，采用两模相反相位调制的PolM引入两个正交极化音调之间的光相移。仿真结果表明，在一个直流偏置电压下，MPPS可以实现360°的连续可调相移，并且由于不使用滤光片，对光载波波长和微波信号频率不敏感。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
