Optical switch and beam direction module

A beam direction module comprising:

• a first supporting member;
• a first collimator supported by said first supporting member for emitting a beam;
• a first substrate disposed opposite to said supporting member;
• a first micromirror disposed on said first substrate;
• a second substrate disposed opposite to said first substrate;
• and
• a second micromirror disposed on said second substrate;
• and
• a mechanism for rotating said first micromirror rotates in a first direction, and rotating said second micromirror in a second direction.

An optical switch for switching optical signals propagating through a plurality of optical fibers, said optical switch comprising:

• an input beam direction module including:
• a first supporting member;
• a first collimator supported by said first supporting member for emitting a beam;
• a first substrate disposed opposite to said supporting member;
• a first micromirror disposed on said first substrate, said first micromirror having a first rotation axis;
• a second substrate disposed opposite to said first substrate;
• and
• a second micromirror disposed on said second substrate, said second micromirror having a second rotation axis;
• and
• an output beam direction module for receiving light from said input beam direction module,
• wherein said second micromirror is arranged such that said second rotation axis extends closer to a direction in which the beam exits from said collimator than said first rotation axis, when viewed from a direction in which said first substrate and said second substrate are stacked.
