Compensation of residual donors in the substrate may additionally be effected by diffusing zinc into the substrate. The device shown has, on the substrate 48 of semi-insulating indium phosphide, indium gallium phosphide or indium aluminium phosphide, an N-type layer 43 and a P-type layer 41 both of indium gallium (or aluminium) phosphide, forming PN junction 45. Contacts 47 and 49 are formed on the faces of these layers, either both of molybdenum or 47 only of molybdenum, with 49 of highly doped indium phosphide. The ends 50 and 51 are perpendicular to the junction and polished, and form a Fabry-Perot echelon through which laser light is emitted when the PN junction is forward biased by a voltage between the contacts. Another device (Fig. 2, not shown) has a layer of indium phosphide (or indium phosphide arsenide) formed on the substrate, a voltage above a threshold level applied between spaced aluminium contacts on the layer causing the device to act as a "three level" oscillator as opposed to conventional GaAs "two level" oscillators.
