OPTICAL SWITCH
First Claim
1. An optical switch comprising:
- a plurality of light input/output ports, each of which has a port group of inputting or outputting a light;
an optical path manipulation unit which has a plurality of optical path switching units of switching an optical path of a light input from an input port in the port group to an optical path toward an output port in the same port group according to each of the light input/output ports; and
a condenser lens which condenses light input from the plurality of light input/output ports on the plurality of optical path switching units corresponding to the port groups and optically couples light input from the plurality of optical path switching units with the plurality of light input/output ports corresponding to the port groups,wherein the input/output optical paths of the plurality of light input/output ports with respect to the condenser lens are parallel to each other between the ports in the same port group and are not parallel to each other between the ports in the different port groups as seen from a direction perpendicular to an arrangement direction of optical waveguides which are the ports in the port groups.

Abstract
An optical switch includes light input/output ports, each having a port group of inputting/outputting a light, an optical path manipulation unit having optical path switching units of switching an optical path of a light from an input port in the port group to an optical path toward an output port in the same port group according to each of the light input/output ports, and a condenser lens condensing light from the light input/output ports on the optical path switching units corresponding to the port groups and optically-couples the light input/output ports with the optical path manipulation unit. The input/output optical paths of the light input/output ports with respect to the condenser lens are parallel to each other between the ports in the same port group and are unparallel to each other between the ports in the different port groups as seen from a direction perpendicular to a port arrangement direction.
