Abstract

A new type of fiber Bragg grating is proposed, which is called sliced fiber Bragg grating. Unlike the regular fiber Bragg grating which is a fiber based working device, the new sliced fiber Bragg grating can be used as a free space component. For example, a sliced fiber Bragg grating can be used as a laser diode external cavity. A multimode fiber Bragg grating written on a 100um core size is cut into small segments of 1 to 2mm. Each end surface of the fiber Bragg grating segment is polished and then coated with an anti-reflection coating. The fiber Bragg grating segment, or sliced fiber Bragg grating, is used to manufacture an external cavity laser diode. The sliced FBG external cavity laser diode bandwidth is reduced from 0.19nm to 0.06nm.
