A waveguide grating with a period of 0 62μm has been built on the glass substrate by special duplicating technique from a master of phase grating.The waveguide grating has been used as coupler of waveguide to experimentally observe that laser beam can be coupled into the waveguide film from above air and the TE mode in waveguide has been excited.
