Abstract
Athermal arrayed waveguide grating wavelength division multiplexers applicable to a relatively wide temperature range. One athermal arrayed waveguide grating wavelength division multiplexer includes a base board including an arrayed waveguide grating chip, wherein the base board and the arrayed waveguide grating chip are divided into a first portion and a second portion through at least one division plane; and a sliding deflection component positioned on the base board including a first end and a second end which are respectively fixed on the first portion and the second portion, the sliding deflection component including: a telescopic rod having a length that changes with temperature variation, a first sidewall and a second sidewall positioned at two ends of the telescopic rod, respectively, and a first deflection limiting piece fixed on one side of the telescopic rod.
