Abstract

PURPOSE:To use a flat chip of square or rectangle to realize a semiconductor laser of low threshold current density and an optical detector of high sensitivity, by forming a device on substrate crystal of a crystalline plane in the vicinity of a cubic crystal plane (n11) [where n>1]. CONSTITUTION:A device is formed on substrate crystal of a crystal plane in the vicinity of a cubic crystal plane (n 11) [where n>1]. Planes (-101) and (1-10) of a plane (111) are more prevailing as a cleavage plane then a plane (011). However, as the value (n) of the plane (n11) grows larger than 1, cleavage of the plane (011) becomes easier, and the plane (011) is completely prevailing in the case of n>3. A semiconductor laser of low threshold current density and an optical detector of high sensitivity can be hence realized by the use of a flat chip of square or rectangle.
