WebInjection molding material is at least partly molded around the at least one exposed fiber end (430) of the optical waveguide (400). In order to more efficiently couple light and obviate the need for additional working steps while post-processing, the first mold part (210) and the second mold part (220) are controlled to different temperatures. WebOct 15, 2024 · One of them called external injection locking (EIL) where an external laser known as the master laser is used to inject photons to another laser called slave laser to increase the modulation bandwidth. The other scheme uses a reflector to feedback part of the optical power into the laser itself, thus known as self-injection locking (SIL).
