Embodiment Construction

[0043] 1, the embodiment of electronically controlled phase-shifting unit among the present invention:

[0044] Compared with the existing technologies such as documents 3 and 4, the biggest innovation of the present invention is that an electronically controlled phase shifting unit is introduced, so that the optical modulator described in the present invention has multiple functions. The electronically controlled phase shifting unit can be used as Figure 5 The two structures shown are:

[0045] Structure 1 Non-resonant optical structure

[0046] The structure is as Figure 5 As shown in (a), including, the optical waveguide 1 (110), generally a ridge-type silicon-based waveguide, provides a basic optical path, and considering the increase of the carrier dispersion effect, the intrinsic silicon material can be doped according to an appropriate concentration to form P-type or n-type semiconductor; the third electrode (120), fixed on the optical waveguide 1 (110), is used to...

Abstract

The embodiment of the invention provides a two-port multifunctional optical modulator for an optical communication system. The device has the following functions that a conventional two-port optical modulator provides the functions of amplitude optical modulation, phase optical modulation and high-order optical modulation; a single-port reflective optical modulator only provides the function of amplitude optical modulation; the single-port reflective optical modulator provides the functions of amplitude optical modulation, phase optical modulation and high-order optical modulation. The two-port multifunctional optical modulator can be applied as part of an integrated optical loop, and can also independently serve as a two-port device. The device is conveniently integrated on a silicone-based optical chip, thus, a low-cost and high-reliability optical module is conveniently formed, and the optical module is applied to optical communication and optical interconnection systems.

Description

technical field [0001] The invention relates to the field of integrated optical devices, in particular to a device with conventional high-order light modulation and reflective high-order light modulation. Background technique [0002] Integrated photonic devices are a key technology in the field of optoelectronics. Due to the development of technology, people have been able to produce passive optical devices such as optical couplers, optical beam splitters, and optical filters, or active optical devices such as optical modulators and electro-optic switches on optical chips made of silicon-based materials. Since silicon-based integrated devices using silicon-on-insulator (Silicon-On-Insulator, SOI) technology are well compatible with CMOS processes, silicon-based devices are easy to mass produce and have cost advantages. Some devices in equipment, optical communication and optical network are integrated on a single silicon-based optical chip, and finally realize the optical ...
