摘要

我们提出并成功模拟了一个使用硅微环调制器的8PSK发生器的一般设计概念。通常，在平衡状态和不平衡状态下，利用同相/正交调制器产生正交相移键控(QPSK)，分别在复平面上呈现方形和矩形星座映射。通过在第一个QPSK调制器的q臂中引入8db损耗，产生了一个不平衡的QPSK调制器。从而级联两个QPSK调制器，合成了光学8PSK。

Optical 8PSK Generation by Cascading Squared and Rectangular QPSK Using Microring Modulators

ABSTRACT We have proposed and successfully simulated a general design concept of an 8PSK generator using a silicon microring modulator. Usually, quadrature phase-shift keying (QPSK) is generated using in-phase/quadrature modulator in balanced condition or in un-balanced condition showing a square-shape and rectangular-shape constellation mapping in complex plane, respectively. By introducing 8 dB loss in the Q-arm of the first QPSK modulator, an unbalanced QPSK modulator has been generated. Thereby cascading both the QPSK modulators, an optical 8PSK has been synthesized.

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.
