Abstract
PURPOSE:To relieve an optical waveguide from excessive loss at nondetecting time by performing effective checking-up with the optical waveguide at signal detecting time only in a photodetector of an optical integrated circuit used in combination with the optical waveguide. CONSTITUTION:Optical waveguide 2 is formed on an n-type InP substrate 1, consisting of a crystal with higher refractive index than and with equal lattice constant to, and further with band width equal to or larger than the above InP substrate 1, in the form of strip. The constitution of the crystal is, for instance, 30Al, 67In, 30p, 70As. In addition, the clad layer 3 of InP is formed and in a part of it one or several p-layers 4 are formed by the diffusion of Cd or Zn to produce pn-junction 5. Optical waveguide 2 and pn-junction 5 are kept at a given distance within the range of 0.1-2mu. In case the distance is less than 0.1mu, both contact with each other due to the unevenness of the diffusion face, and in case it is more than 2mu, coupling is insufficient. In this constitution, the photo-detector connects with the optical waveguide only at the time of signal detection (bias) but gives almost no effect thereto at other times.
