Abstract
A transmissive photonic crystal fiber ring resonator employing single optical beam-splitter comprises: a first fiber-optic collimator, a second fiber-optic collimator, a first photonic crystal fiber collimator, a second photonic crystal fiber collimator, an optical beam-splitter, and a fixture. The first fiber-optic collimator, the second fiber-optic collimator, the first photonic crystal fiber collimator, the second photonic crystal fiber collimator, and the optical beam-splitter are fixed on the fixture; the fiber pigtails of the first fiber-optic collimator and the second fiber-optic collimator are the input/output ports; the fiber pigtails of the first photonic crystal fiber collimator and the second photonic crystal fiber collimator are connected. The number of components of the photonic crystal fiber ring resonator is reduced by half: only one optical beam-splitter and two photonic crystal fiber collimators besides two fiber-optic collimators; therefore, the resonator structure can be simplified and the size can be reduced.
