Title: Production of diffraction grating
Inventor: TSUBOTA TAKASHI
IPC: G02B5/18
Filed: 1990-12-18
Abstract: PURPOSE:To obtain stable diffraction efficiency by forming the diffraction grating by etching a substrate until the specified shape of the diffraction grating is obtd. CONSTITUTION:The InP substrate 31 is coated with a photoresist film 32 and interference patterns of a prescribed pitch are exposed thereto by luminuous flux interference exposing. This resist film is then developed to form etching mask patterns 33 for forming the diffraction grating. The diffraction grating patterns 34 are thereafter transferred by a prescribed etching liquid. The etching time is about 30 seconds and the diffraction grating patterns 34 of a saw tooth wave are formed in this way. The etching mask patterns 33 are then removed. Further, an InP layer 35 is subjected to crystal growth by for example, a liquid growth method. This InP layer 35 is grown to the groove parts of the diffraction grating patterns 34 of the saw tooth shape. Then, the diffraction efficiency of the diffraction grating is controlled by the growth layer thickness of the InP layer 35.
