Highly efficient broadband conversion of light polarization by composite retarders.
Driving on an analogy with the technique of composite pulses in quantum physics, we propose highly efficient broadband polarization converters composed of sequences of ordinary retarders rotated at specific angles with respect to their fast-polarization axes.
متن کاملEfficient Superfluorescent Light Sources with Broad Bandwidth
We demonstrate various efficient broad-band light sources at ~1μm wavelength with a 3dB bandwidth of up to 65nm at 108mW output power, based on rare-eartb doped silica fibers and a simple adjustable spectral filter.
متن کاملFrequency conversion of structured light
Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel applications in photonic technology and fundamental science. In particular, frequency conversion of spatial modes carrying orbital angular momentum can be exploited in sub-w...
متن کاملFrequency and bandwidth conversion of single photons in a room-temperature diamond quantum memory
The spectral manipulation of photons is essential for linking components in a quantum network. Large frequency shifts are needed for conversion between optical and telecommunication frequencies, while smaller shifts are useful for frequency-multiplexing quantum systems, in the same way that wavelength division multiplexing is used in classical communications. Here we demonstrate frequency and b...
متن کاملEfficient and exact quantum compression
We present a divide and conquer based algorithm for optimal quantum compression / decompression, using O(n(log n) log log n) elementary quantum operations . Our result provides the first quasi-linear time algorithm for asymptotically optimal (in size and fidelity) quantum compression and decompression. We also outline the quantum gate array model to bring about this compression in a quantum com...
