Abstract:
1. A method of calibrating an optical switch including a first port, a second port, a first mirror and a second mirror, the method comprising: directing a first beam of light onto said first mirror; directing a second beam of light onto said second mirror; controlling an orientation of said first mirror such that said first mirror reflects said first beam of light to a predetermined position on a first position sensing detector, thereby directing a third beam of light incident on said first mirror from said first port to said second mirror; controlling an orientation of said second mirror such that said second mirror reflects said second beam of light to a predetermined position on a second position sensing detector, thereby directing said third beam of light to said second port; controlling said orientation of said first mirror and said orientation of said second mirror to maximized an intensity of said third beam of light coupled into said second port; and recording signals determined from outputs of said first and said second position sensing detectors.
