摘要： An optical deflector includes a plurality of piezoelectric unimorph oscillating bodies (210a to 210d) that cause a reflecting plate (1) to oscillate rotationally, centering upon a pair of flexible support units (2a and 2b). The optical deflector forms a single structure of the oscillating plates (23a to 23b), the reflecting plate (1), the flexible support units (2a and 2b), and a support body (9), by connecting one set of the terminals of the oscillating plates (23a to 23d) of the suite of piezoelectric unimorph oscillating bodies (210a to 210d) to the flexible support units (2a and 2b), and connecting the other set of terminals to the support body (9). Furthermore, the plurality of piezoelectric unimorph oscillating bodies (210a to 210d) each respectively comprise a plurality of parallel oscillating bodies (23a1 to 23a-3, 23b-1 to 23b-3, 23c-1 to 23c-3), and (23d-1 to 23d-3), and a suite of parallel actuators (28a-1 to 28a-3, 28c-1 to 28c-3, and 28d-1 to 28d-3).

摘要： A light emitting element has plural semiconductor layers including a light emitting layer and formed on one principal surface of a semiconductor substrate, and is constructed such that at least one portion of end faces of the plural semiconductor layers including the light emitting layer is set to a light emitting end face. Plural light emitting end faces are formed in the light emitting element. Angles formed between mutual adjacent end faces of the respective light emitting end faces are set such that lights emitted from at least two light emitting end faces among the plural light emitting end faces are mutually synthesized. Accordingly, lights from the plural light emitting end faces can be synthesized and emitted. As a result, an amount of light emitted in a forward direction of the light emitting element and an output of this light can be increased. Accordingly, coupling efficiency of the light emitting element and an optical fiber can be improved and a reduction in light emitting efficiency can be effectively prevented.
