INTEGRATED RESONATOR MATRIX FOR SELECTIVE WAVELENGTH SEPARATION OR JOINING OF CHANNELS IN THE FREQUENCY RANGE OF OPTICAL COMMUNICATIONS TECHNOLOGY

摘要

Arrangement of optical resonators consisting of dielectrical wave guides which on the ends are made reflectant with reflectors having a high reflection coefficient close to the value of one, and whose longitudinal elongation between the reflectors is great as compared to the corresponding perpendicular cross measurements; characterized by the fact that all the optical resonators are integrated on a substrate in a matrix-like arrangement, called a ''resonator matrix'', in such a way that two types of resonators can be distinguished, resonators of the first type being strongly coupled among themselves and function as coupled resonators (22, 221, 222), whereas the resonators of the second type function as selective wavelength effective resonators (23, 231, 232), and are weakly coupled either among themselves or to resonators of the first type as compared with the coupling among resonators of the first type; at least two effective resonator groups are formed which are not coupled among themselves, or coupled as little as possible, an effective resonator group containing one or more effective resonators.
