Patent ID: 7085448

Claim:
An optical wavelength control system for an optical source, the system including: a beamsplitter arrangement for propagating radiation from said source over two paths; first and second photodetectors each arranged in a respective one of said two propagation paths; a wavelength selective optical filter interposed in the propagation path from said source to said first photodetector, whereby said first and second photodetector are adapted to generate photocurrents indicative of the possible displacement of the actual wavelength of the radiation from said source with respect to a reference wavelength and the power emitted by the optical source, respectively; and a support bench extending in a given plane, wherein said beamsplitter arrangement is arranged to split said radiation from said source towards said first and second photodetectors in a direction substantially perpendicular said given plane of said bench, and wherein said beamsplitter arrangement, said optical filter and said photodiodes comprise an assembly having an associated a frame carrying said beamsplitter arrangement, said optical filter and at least one of said photodiodes oriented at pre-set angles.
