Waveguide array interferometer

Abstract

The present invention relates to a waveguide technology and is one kind of waveguide array interferometer with wide application especially as kernel part in light communication network, light information transmitting and processing system, spectral measurement, sensing, laser device and integrated photoelectronic device. The waveguide array interferometer includes input light waveguide, output light waveguide, and waveguide array, linear and / or curved, on carrier between the input light waveguide and the output light waveguide. The present invention has the advantages of very high wavelength resolution or very narrow channel, modular structure and insertion loss not increasing with increased channel number. The waveguide array interferometer may be manufactured with high repeatability in the light mask technology similar to that in large-scale IC manufacture.

Description

technical field

[0001] The invention relates to an arrayed waveguide interferometer, which belongs to the field of waveguide technology, and is especially suitable as a core device or key component of an optical communication network, optical information transmission and processing system, spectral measurement, sensing, laser device, and integrated optoelectronic device. Background technique

[0002] Traditional interferometers include Fabry-Perot interferometers, Mach-Zehnder interferometers, Michelson interferometers, etc., which are widely used in various fields such as spectral analysis, laser devices, precision measurement, and photoelastic analysis. Many fiber optic sensors, such as stress, For strain, temperature, magnetic field optical fiber sensors, etc., a section of sensitized optical fiber that plays a sensing role is also used as a part of the above-mentioned interferometer to achieve sensing and measurement. In recent years, the rapid development of optical com...
