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. WebAbstract Two single-mode laser diodes have been injection locked to the +1 and −1 diffracted orders of a 4.6-GHz acousto-optical modulator. The measured locking bandwidth was 3 GHz for a locking gain of 35 dB. The microwave signal at 9.2 GHz had a measured linewidth of less than a few hertz.
