Abstract

The invention relates to a femtosecond laser processing device and a 1x8 ridge type optical splitter processed through device. When an optical device is processed through the femtosecond laser processing device, femtosecond pulsed laser beams sequentially pass through a half wave plate, a mirror and a microscope objective and then are focused to a substrate material fixed on a six-degree-of-freedom working platform, the focused femtosecond pulsed laser beams lithograph the substrate material into the optical device in the movement process of the six-degree-of-freedom working platform, and airflow between a blowing part and a sucking part is used for dedusting in the lithography process. The processing device is simple in structure, and the optical device processed by the processing deviceis low in processing cost, high in precision and good in consistency.

Description

technical field [0001] The invention belongs to the field of laser processing, and in particular relates to a femtosecond laser processing device and a 1x8 ridge optical splitter processed therewith. Background technique [0002] With the birth of lasers and the outstanding contribution of quartz glass optical fibers using cladding materials to reduce losses proposed by Kao et al., the application of light in communications has a foundation, and optical fibers are the original waveguides. As a basic component of a passive optical network, an optical splitter is used for power coupling and redistribution of optical signals. It can confine light waves in a medium with the size of the light wavelength and transmit them over long distances without radiation. It has the characteristics of wavelength insensitivity, small size, high reliability, good uniformity of light beam splitting, and wide working wavelength range. At present, methods such as chemical etching and ion etching...
