Abstract: An apparatus for shared optical performance monitoring (OPM) is provided. A wavelength sensitive device receives light at an input port and routes it wavelength selectively to a set of output ports. To perform optical performance monitoring on the output ports, a monitoring component of each output signal is extracted, and these monitoring components are then combined. A single OPM function is then performed on the combined signal. However, with knowledge of the wavelengths that were included in each output signal, a virtual OPM function can be realized for each output port. The per port functionality can include total power per port, power per wavelength per port, variable optical attentuation, dynamic gain equalization, the latter two examples requiring feedback.

Abstract: A return-to-zero (RZ) modulator for an optical transmitter comprises a Mach-Zehnder interferometer optically coupled with a light source for modulating a continuous wave generated the said light source with a drive signal. A drive circuit generates a drive signal for modulating the Mach-Zehnder device to generate an optical RZ pulse signal with adjustable width. The drive circuit comprises a trigger flip-flop for converting a non-return to zero (NRZ) signal to a modified drive signal. A method of generating an optical RZ pulse signal comprises converting a non-return to zero (NRZ) signal to a modified drive signal, and modulating a continuous wave from a light source with the modified drive signal to generate an optical RZ pulse signal. The width of the pulses in the optical RZ pulse signal is controlled by adjusting the rise and fall time of the modified drive signal.
