Micro Capillary Coating for Wavelength Division Multiplexer using interference Filter and Grade Index Lens

摘要

The invention in the manufacture of a filter wavelength stapler using a dielectric thin film, a micro-half four cache heat tape on the capillary tip to improve wavelength separation of the half-division incoming stage only screening fine cache, including a half division capillary the front of the dielectric coating, by a half division only type interference filter of a dielectric coating with a green lens, it characterized in that the coated dielectric coating only to a half wavelength division provides a stapler method.
