Patent ID: 8639070

Claim:
An apparatus, comprising: a support structure having a planar surface; a planar integrated dispersive optical element being fixed to the planar surface, the planar integrated dispersive optical element having an array of first optical ports on a first edge thereof and an array of second optical ports on a second edge thereof; an array of optical devices being fixed to the planar surface, each of said optical devices being connected to a different one of the second optical ports, the number of second optical ports being greater than the number of said optical devices; and an optical relay system connected to transmit light between an optical fiber coupler and a selected one of the first optical ports, the optical relay system including a first mirror located on a rail on the planar surface, the rail being such that moving the first mirror there along causes the optical relay system to transmit light between the optical fiber coupler and another of the first optical ports; and wherein the optical relay system further comprises a first lens mounted on the rail.
