Claim:
1. An optical wavelength dispersion device, comprising: a first substrate; an input unit, which is formed on the first substrate, having a slit for receiving an optical signal; a grating formed on the first substrate for producing a diffracted light beams from the optical signal; a first optical reflector formed on the first substrate for reflecting the diffracted light beams from the grating for outputting; a second optical reflector formed on the first substrate for reflecting the diffracted light beams from the first optical reflector in such a manner that an external sensor is capable of being positioned in any direction near the optical wavelength dispersion device; an output unit for outputting the diffracted light beams; and a second substrate covered on the top of the input unit and the grating; wherein the input unit, the first optical reflector, the second optical reflector and the grating are formed from a photo-resist layer being exposed under high energy light source exposure through a high energy light source mask, wherein the wavelength of the high energy light source is from 0.01 to 100 nm, wherein the first substrate and the second substrate define an optical waveguide space therebetween, wherein the input unit, the grating, the first optical reflector and the second optical reflector are respectively provided in the optical waveguide space.
