Patent ID: 7072031

Claim:
Apparatus for alignment of a first input mirror and a first output mirror in a photonic cross-connect, said apparatus comprising: a first port and a second port selectively connected to one another over a first optical datapath therebetween, said first optical datapath containing said first input mirror and said first output mirror therein; a first alignment laser optically connected to said first optical datapath so as to selectively inject light along said first optical datapath, wherein said light injected along said first optical datapath is analyzed to provide feedback data for alignment of said first input mirror and said first output mirror; and a second optical datapath between said first port and said second port, said second optical datapath containing a second input mirror and a second output mirror therein, and a second alignment laser optically connected to said second optical datapath so as to selectively inject light along said second optical datapath, wherein said light injected along said second optical datapath is analyzed to provide feedback data for alignment of said second input mirror and said second output mirror.
