Abstract
An optical wavelength dispersion device is disclosed, which includes a waveguide unit and an adjustable reflecting unit, wherein the waveguide unit has a first substrate, an input unit, a grating, a reflector and a second substrate. The input unit is formed on the first substrate and having a slit for receiving an optical signal, a grating is formed on the first substrate for producing an output beam once the optical signal is dispersed, the reflector is formed on the first substrate for reflecting the output beam, the second substrate is located on the input unit, the grating and the reflector, and forms a waveguide space with the first substrate; the adjustable reflecting unit is located outside of the waveguide unit, and is used for changing emitting angle and adjusting focus of the output beam.
