A wavelength-tunable fiber-coupled source of narrowband entangled photons.
We demonstrate a wavelength-tunable, fiber-coupled source of polarization- entangled photons with extremely high spectral brightness and quality of entanglement. Using a 25 mm PPKTP crystal inside a polarization Sagnac interferometer we detect a spectral brightness of 273000 pairs (s mW nm)(-1), a factor of 28 better than comparable previous sources while state tomography showed the two-photon ...
متن کاملNarrowband, polarization insensitive all-fiber acousto-optic tunable bandpass filter.
We demonstrate an all-fiber acousto-optic tunable bandpass filter exhibiting narrow optical bandwidth and negligible polarization dependence by employing a novel ultraviolet (UV)-induced core-mode blocker written in a high numerical aperture (NA) fiber. It was demonstrated that the device had the measured 3-dB optical bandwidth of 0.65 nm, the polarization-dependent center-wavelength splitting ...
متن کاملPolarization 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 کاملTunable multiwavelength fiber laser using a comb filter based on erbium-ytterbium co-doped polarization maintaining fiber loop mirror.
A tunable comb filter based on a fiber loop mirror setup, which incorporates a piece of pumped erbium-ytterbium co-doped polarization maintaining fiber, is newly presented. It is accomplished by controlling the pump power or adjusting a polarization controller in the loop mirror, which results from the fact that the effective birefringence of the erbium-ytterbium co-doped polarization maintaini...
