    • The invention relates to an optically pumped multilayered modulator having surface-normal geometry. The multilayer structure comprises an absorber section through which an optical signal (401) to be modulated is coupled from an input (400) to an output (400). The multilayer structure further comprises control means for supplying a control signal for controlling the transmission characteristics of the absorber section, The control signal is generated by an in-plane waveguide-type laser integrated monolithically with the saturable absorption region. The in-plane control laser includes waveguide regions (405) and multiple-quantum-well layers (409) used as a gain medium. The laser beam is adapted to travel through the absorber section in order to modulate the transmission characteristics of the absorber section.

    • Controlled laser having an optical resonator (102, 106), a laser gain medium placed inside the optical resonator the laser gain medium being capable of emitting light and of lasing with the light, a multiple layer heterostructure (110) placed inside the optical resonator, and means for varying an optical absorption of the multiple layer heterostructure for the light in order to control an optical gain of the optical resonator, and thereby control lasing of the laser gain medium. Passive mode locking is achieved by the light emitted by the gain medium controlling the optical absorption of the multiple layer heterostructure. Active mode locking and modulation are achieved by controlling the optical absorption of the multiple layer heterostructure by applying an electric field to the multiple layer heterostructure. Control of laser gain by an external light source is achieved by controlling the optical absorption of the multiple layer heterostructure by illuminating it with light from the external light source. An embodiment of the multiple layer heterostructure fabricated as a GaAsAlGaAs multiple quantum well with a Type I superlattice band structure is a passive mode locker for a semiconductor diode laser.
