Abstract:
A vertical cavity surface emitting laser emitting light at a first wavelength longer than a second wavelength of the light used for optically pumping it comprisinga substrate supporting a stack of layers, the stack comprising in turn: a first section forming a first mirror highly reflective of the light of the second wavelength; a second section forming the cavity of a laser emitting at the second wavelength and including the gain medium of the laser; a third section forming a second mirror reflective of the light of the second wavelength and partially transmissive of light of said second wavelength, the first, second, and third sections forming a vertical cavity surface emitting laser emitting at the second wavelength; a fourth section forming a mirror highly reflective of the first wavelength and transmissive to light of the second wavelength; a fifth section forming the cavity of the laser emitting at the first wavelength and including the gain medium of such laser; and a sixth section forming a mirror reflective of the first and second wavelengths and partially transmissive of light of the first wavelength, characterized in that the third and sixth sections are spaced to establish a standing wave of the second wavelength therebetween and that the first, second, third, fourth, and fifth sections are epitaxial with the substrate.
