摘要
In this paper, we propose a compact and integrated optical spectrum analyzer (OSA) based on ring resonator. In this design thermo-optic, electro-optic, acousto-optic and nonlinear optic effects can be used as control signal to sweep the output frequency. The applied control signal changes the index of refraction and therefore the resonance frequency and the trapped optical intensity are changed corresponds to the input signal contents. Also, the proposed idea can easily be integrated on optical single chips. The presented design idea is simple for realization and implementation using optical integrated circuits, has high accuracy (less than 4pm) and compact. This new proposed OSA is suitable for wavelength-division-multiplexing performance monitoring that requires high speed and high wavelength measurement.
