Abstract

We investigate the magnetooptical effects in near-infrared wave properties for a semiconductor-based photonic crystal (PC) containing n-type InSb. We find that the static magnetic field serves as an externally switching and tuning agent in the wave transmission near 1.54 μm. With the applied static magnetic field, an additional small transmission gap, which does not appear in the absence of static magnetic field, can be opened up. The position of this gap can also be further tuned by the variation in this static field. The analytical results near this wavelength reveal that such a semiconductor PC can work as a magnetically tunable notch filter, which will be informative and of technical use to signal processing in optical communications.
