OPTICAL MODULE HAVING COMPOSITE PRISM TO MULTIPLEX OPTICAL BEAMS

摘要

An optical module that installs a plurality of laser diodes (LDs) and a composite prism to condense optical beams emitted from the LDs is disclosed. The LDs are arranged on a line so as to level the optical beams within a plane. The composite prism includes input surfaces and output surfaces each corresponding to respective one of the input surfaces. The composite prism outputs optical beams whose intervals are narrowed compared with intervals of the optical beams entering therein.

1. An optical module, comprising:
a plurality of laser diodes (LD) configured to emit optical beams; a plurality of collimator lenses, each being optically coupled with respective one of the LDs and collimating respective one of the optical beams; a composite prism providing a plurality of input surfaces and a plurality of output surfaces, the input surfaces receiving optical beams output from respective collimator lenses, the output surfaces outputting respective optical beams; and a condenser lens having an optical axis, the condenser lens configured to focus the respective optical beams output from the output surfaces of the composite prism on an end of an external fiber, wherein the composite prism reduces intervals between optical beams entering therein to output the optical beams with reduced intervals.
