Abstract
A dynamic optical wavelength balancer is described. The apparatus includes a plurality of wavelength selective reflectors. Each wavelength selective reflector reflects optical signals at a predetermined one optical wavelength selected from a plurality of predetermined optical wavelengths. A bi-directional optical variable coupler array has a first port and a plurality, N, of second ports. Each wavelength selective reflector is coupled to a corresponding one of the second ports. The bi-directional optical variable coupler array is responsive to control signals for establishing different degrees of optical couplings between the first port and selected ones of the plurality of second ports.
