A bidirectional fiber-IVLLC and fiber-wireless convergence system based on two orthogonally polarized optical sidebands for hybrid CATV/MMW/BB signal transmission is proposed and demonstrated. Two orthogonally polarized optical sidebands are transmitted over a 40-km SMF transport to effectively reduce the fiber dispersion and the distortion. The approach presented in this work signifies the advancements...
We propose an infrared tunable dual-band polarization filter in this paper. Based on the perfect absorption characteristic of the metal-dielectric-metal sandwich structure, the reflection spectrum performs as a filter. The calculated results show that different dual-band wavelengths are filtered while the incident light has different polarization which is parallel or vertical to the x axis. Moreover,...
Multiform spectral shaping schemes to provide tunability on the shape, free spectral range and bandwidth of microwave photonic signals are reviewed. By utilizing specific dispersion-based conversion techniques, the proposed scheme scan be widely used to achieve flexible manipulation of microwave signals.
PMD mitigation in 2×10-Gb/s RZ-OOK PDM systems is demonstrated through a single all-optical-regenerator with polarization-diversified loop configuration. 3.0-dB eye-diagram-based SNR improvement is achieved in the presence of 6.3-ps DGD for RZ signals with 18-ps pulsewidth.
We demonstrate the fabrication of polymer microring add-drop filters using multiphoton absorption polymerization and present the characterization of these devices.
A one-dimensional photonic bandgap lattice consisting of 72 periodically-cascaded microrings was fabricated in benzocyclobutene. A wide bandgap of 1.6 nm and extinction > 20dB were achieved. The device exhibited low transmission loss even after 72 microrings.
Ultrahigh resolution endoscopic OCT using a broadband Cr4+ :forsterite laser light source is demonstrated in vivo in the rabbit. Imaging of the esophagus was performed with <4 mum axial resolution in tissue and correlated with histology
