1. An active optical system for wavelength division multiplexing (WDM) used with an optical fiber, the active optical system comprising:
a transmitter module, the transmitter module comprising:
a plurality of first vertical-cavity surface-emitting lasers (VCSELs), each being configured to emit an optical signal;
at least one first photodiode being arranged in parallel to the first VCSELs and being configured to receive at least one feedback signal;
a first array having first lenses, the first array of lenses disposed in optical communication with the first VCSELs and the at least one first photodiode, respectively;
a first Z-block-shaped prism having a plurality of incident faces, an exit end, and at least one output face, the incident faces disposed in optical communication with the first array of lenses, respectively, and the at least one output face disposed in optical communication with the at least one photodiode, wherein the exit end is configured to output the optical signals to a first end of the optical fiber and receive at least one feedback signal incident therefrom.
