摘要： An external optical resonator for a semiconductor laser is composed of an optical directional coupler which can be formed as an integrated optical coupler with a short structural length that enables a free spectral range in the order of 100 GHz and enables the resonator and the system fiber to be coupled to the same end face of the laser. The resonator structure includes two optical waveguides with feedback means applied on the end faces of one of the waveguides and the other waveguide having one end face coupled to receive the output of the laser and the other end face of the other waveguide being coupled to the system fiber. The arrangement is particularly useful for tunable semiconductor lasers, particularly for heterodyne reception.

摘要： A switch for optically connecting a first light conducting fiber selectively with at least one second light conducting fiber characterized by a first light conducting fiber having a magnetic sleeve adjacent the free end thereof, at least one second light conducting fiber, a substrate having a first flat surface with a layer being disposed on the first flat surface and having a recess with a groove for each of the first and second fibers extending therefrom. Each of the second fibers is disposed in its respective groove with the free end extending into the recess and the first fiber is disposed in its groove with its free end which has the magnetic sleeve being mobile in the recess between a first position forming an optical connection with one of the second fibers and a second position out of optical connection with one of the second fibers so that an application of an external magnetic field causes the free end of the first fiber to move between the first and second positions. One of the preferred methods of forming the switch comprises providing a substrate having a layer of light sensitive material disposed thereon, exposing the light sensitive material through a mask of a desired configuration, developing the exposed light sensitive layer to produce the recess with the grooves extending therefrom so that the fibers are clamped in the grooves with their ends extending into the recess to form the switch.
