Abstract
The utility model discloses a detector structure suitable for wavelength-division multiplexing and belongs to photoelectric technical field. A spiral micro cavity structure is formed by splicing two or more than two sector structures or sector annular structures in a front and back manner. Each sector or sector annular structure is provided with a groove used for being connected with an incoming wave and used as an input interface of each channel signal. The openings of the grooves have same direction and are arranged clockwise or counter clockwise in order to guarantee incident signal light to be restricted to the micro cavity. Each channel corresponds to a micro cavity resonant wavelength. Multipath signal light can be detected by a single detector such that cost is greatly decreased. RC delay is reduced by designing the micro cavity in micrometer magnitude such that the bandwidth of the detector is greatly widened. Since the openings of the grooves are all arranged in same direction, not an output channel is provided for the input signal light. Therefore, all signal light are restricted to the micro cavity until to be adsorbed completely. Thus, the sensitivity of the detector is increased.
