Polarization Selective Wavelength Tunable Filter
In conventional color CCD cameras, each color pixel consists of different pixels that record the red, green or blue light. However, for special applications such as in astronomy, it is desirable to take pictures at a number of specific wavelengths. In this work, we present the design and fabrication of a liquid crystal wavelength tunable filter which is also able to detect the polarization stat...
متن کاملAn upstream multi-wavelength shared PON based on tunable self-seeding Fabry-Pérot laser diode for upstream capacity upgrade and wavelength multiplexing.
We proposed an Upstream Multi-Wavelength Shared (UMWS) PON architecture based on a tunable self-seeding Fabry-Perot laser diode (FP-LD) at ONU. The performances of the wavelength and power stability, side-mode suppression ratio (SMSR), tuning range for the proposed tunable self-seeding laser module at ONU are experimentally investigated. The BER is measured with direct modulation on FP-LD of 1....
متن کاملTunable optical tweezers for wavelength-dependent measurements.
Optical trapping forces depend on the difference between the trap wavelength and the extinction resonances of trapped particles. This leads to a wavelength-dependent trapping force, which should allow for the optimization of optical tweezers systems, simply by choosing the best trapping wavelength for a given application. Here we present an optical tweezer system with wavelength tunability, for...
متن کاملBroadband single-mode operation of standard optical fibers by using a sub-wavelength optical wire filter.
We report the use of a sub-wavelength optical wire (SOW) with a specifically designed transition region as an efficient tool to filter higher-order modes in multimode waveguides. Higher-order modes are effectively suppressed by controlling the transition taper profile and the diameter of the sub-wavelength optical wire. As a practical example, single-mode operation of a standard telecom optical...
متن کاملOptical Correlation with Light of Tunable Wavelength
A novel method is described for compensation of size variations in the input pattern of an optical correlator for pattern recognition by appropriate adjustment of the reconstruction wavelength. Simple ring-shaped patterns of variable diameter have been optically cross-correlated. Using a tunable dye laser of narrow bandwidth, the correlator output was analyzed for various combinations of size a...
