Embodiment Construction

[0020] The heated arrayed waveguide grating AWG module of the present invention will be further described below in conjunction with specific embodiments.

[0021] In this embodiment, a chip dedicated to temperature control is used as the main temperature control. The temperature control chip and the peripheral heating circuit are marked with reference number 2. The main temperature control realizes heating through the heating component 3, and through the The temperature sensor 9 controls the temperature of the module to set the target temperature, and the main temperature controller feeds back the heating temperature to the main control chip 1 through the electrical signal 6. The main control chip 1 adopts a 32-bit MCU, on which the heating array waveguide of the present invention runs The program of the grating (AWG) module, the main control chip 1 obtains the temperature control status of the main temperature control circuit through the electrical signal 6 fed back by the mai...

Abstract

The invention relates to a heating-type AWG (Array Waveguide Grating) module. The heating-type AWG module is characterized in that heating reliability is improved by using a main heating control circuit and a standby heating control circuit, wherein the main heating control circuit is composed of independent temperature control circuit and includes a temperature control chip and a peripheral circuit and a temperature sensor; the standby heating control circuit is composed of a main control device of the heating-type AWG module itself, a heating current control device and a temperature sensor.The main heating control circuit and the standby heating control circuit share a heating assembly, so that the standby heating circuit is added at a comparatively low cost and the reliability is improved.

Description

technical field [0001] The invention relates to a heated array waveguide grating (AWG) for optical communication wavelength division multiplexing, in particular to a heated array waveguide grating (AWG) module with a highly reliable heating circuit. Background technique [0002] In the current field of optical communications, arrayed waveguide gratings (AWG) are widely used in wavelength division equipment, and heated AWGs occupy the main application market due to their low cost advantages. In such applications, precise heating and temperature control circuits are key components , in order to meet the requirements of the module to ensure the normal operation of the AWG when the main control chip is upgraded online or the program of the main control chip is abnormal, an independent temperature control circuit is often used, but any circuit always has a certain probability of failure , when the temperature control circuit fails, the AWG working wavelength will shift, which wil...
