Patent ID: 7136554

Claim:
A post packaging alignable optical coupling comprising: a base; a first optical element for receiving or transmitting an optical signal, said first optical element located in a fixed condition on said base; a second optical element fixedly mounted to the base for receiving or transmitting an optical signal wherein at least one of the optical elements is an optical fiber or optical waveguide; a mirror interposed to directly intercept an optical signal from one or the other of said optical elements, said mirror moveably disposed with respect to said base; a MEMS actuator, said MEMS actuator supporting said mirror to enable repositioning said mirror to thereby direct the optical signal directly intercepted by said mirror from said first optical element into alignment with said second optical element or vice versa; and a shroud encompassing said optical elements with a free space located between said optical elements to therein enable remotely repositioning the mirror with the MEMS actuator when the shroud extends over the optical elements.
