Title
(EN) Optical transmitter comprising a stepwise tunable laser
Abstract
(EN)
A laser, useful as part of a multiple wavelength optical fiber transmitter, includes a single mode, multiple quantum well semiconductor amplifying mirror as a gain element an includes a second mirror to form an optical cavity, the length of which defines a sequence of optical modes. The gain element has an arrangement for tuning the laser from one mode to another by altering a temperature of the amplifying mirror.
