Embodiment Construction

[0019] figure 1 The arrayed waveguide interferometer-based optical passive device with built-in optical gain function includes a 1×N demultiplexer composed of arrayed waveguide interferometers 1,...,N, whose operating wavelengths are λ 1 ,,...,λ N , in the arrayed waveguide interferometer 1, the forward pump light λ P Directly input from the left port of its output optical waveguide I2, the reverse pumping light λ p It is input from the pump light input channel P1 formed by the Y-shaped structure at the right port close to I2. Since I2 is made of an optical waveguide with a gain function, the output optical signal λ 1 The gain obtained during transmission can offset the optical loss to a certain extent, and even the gain is greater than the loss to achieve optical amplification. To avoid the pump light λ p , through a pump light separation channel P2 composed of a directional coupler, the λ p Separated so that it is not output from the right output port of the output chan...

Abstract

The invention discloses an inserted optical-gain optical passive device based on the array wave guide interferometer, adopting the optical wave guide material with the gain function, and at the same time integrating the pumping riverside input channel, the pumping riverside optical separate channel and the signal light intensity detecting channel in it, the inserted loss low, and even able to realizing the optical amplification.

Description

technical field [0001] The invention relates to an optical passive device based on an arrayed waveguide interferometer with a built-in optical gain function, belongs to the field of integrated optics, and is especially suitable for being an optical communication network device. Background technique [0002] Arrayed waveguide interferometer (AWI) is a new type of interferometer that adopts the principle of multi-beam interference. It has very high wavelength resolution. Multiple AWIs can be connected in series in a certain way to form various optical passive devices. , such as wavelength demultiplexer / wavelength multiplexer (WDMUX / WMUX, Wavelengthdemutipler / wavelength mutiplexer) based on arrayed waveguide interferometer, wavelength selective switch (WSS, Wavelength-selective switches) based on arrayed waveguide interferometer, based on arrayed waveguide interference wavelength-selective routing (WSR, wavelength-selective routing), wavelength-selective co...
