ABSTRACT:
Optical, opto-electronic or photonic component comprising, for a given operating wavelength, at least one optical cavity defined between two reflectors and confined laterally. The reflectors are of the phase change type and the area between the reflectors that corresponds to the optical cavity has a cut-off wavelength greater than the cut-off wavelength of the area surrounding it laterally, the operating wavelength lying between the two cut-off wavelengths. The method enables manufacture of a component of this kind using relatively shallow etching.
