Abstract
An optical monitor that generates a signal indicative of at least two optical properties of an input optical signal. The monitor utilizes a polarization dependent beam splitter having a signal input port, a mixing signal input, a first output port and a second output port. The signal input port receives an input optical signal having first and second orthogonal polarization components. The mixing signal input receives an optical mixing signal having a first and second polarization component parallel to the first and second polarization components of the optical input signal, respectively. The polarization dependent beam splitter generates first and second output signals on the first and second output ports, respectively. The output signals are the sum of the like polarization components of the input optical signal and the optical mixing signal.
