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 wavelength is λ p The forward pumping light is directly input from the left port of its output optical waveguide I2, and the wavelength is λ p The reverse pump light is input from the pump light input channel P1 formed by the Y-shaped structure near the right port of 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 a wavelength of λ P The effect of the pump light, through a pump light separation channel P2 composed of a directional coupler to put λ P Separated so ...
