A telecommunications switch system utilizes a laser cathode ray tube (Laser-CRT) including a faceplate having a plurality of laser pixels. A driver and control system control an electron beam to energize a selected laser pixel and thereby provide laser emission from the selected laser pixel. The laser emission from each pixel (an optical signal) is provided to an optical distribution system such as a plurality of optical fibers that directs the laser emission to one of a plurality of destinations. The faceplate can have multiple groups of laser pixels, each group providing a different wavelength. In some embodiments the Laser-CRT includes a plurality of electron guns. Some embodiments include an optical multiplexer that multiplexes a number of optical signals into a single optical fiber (N:1). Alternative switch configurations are disclosed, such as an optical-to-optical switch. The Laser-CRT system can be implemented to meet a variety of needs, such as optical switching, DWDM, and optical signal regeneration.
