Abstract
Resonant cavity diode, operating at the same wavelength for emission and detection of light. This diode is particularly applicable to telecommunications and comprises a resonant cavity () delimited by two mirrors () and containing an active medium () and at least two insulating and coaxial rings () with the same inside diameter and the same outside diameter, the total thickness of the rings being provided such that the optical length of the resonant cavity is k×λ (k≧2), in the part of this cavity that passes through the rings, and is (k−1)×λ in the part containing these rings, where λ is the wavelength at which the diode is capable of emitting and detecting.
