Title: Wavelength selecting mode coupler and method of mode coupling of light energy
Inventor: KUREIGU DEI PUURU
IPC: G02B6/34
Filed: 1990-11-13
Abstract: PURPOSE: To provide a mode coupler which can be easily used without requiring accurate alignment at the time of application of filtering by bringing about annular symmetrical perturbation between an input point and an output point and propagating the optical energy, which is received in a first mode at the input point, through the annular symmetrical perturbation to wavelength- selectively couple it to another mode before transmission from the output point. CONSTITUTION: In a wavelength selective mode coupler 300, a single wire 302 is continuously spirally wound around a waveguide 301. This single wire 302 is wound close to bring about annular symmetrical perturbation in the waveguide 301. In this case, annular symmetrical perturbation is defined to bend the waveguide in all directions from 0 to 360 deg. around the axis of the waveguide before bending. By this annular symmetrical perturbation, it is unnecessary to accurately align the direction of micro bending of a cascaded element. Thus, this mode coupler has a very high wavelength dependency, and filtering can be applied.
