Complex decorrelation averaging in optical coherence tomography: a way to reduce the effect of multiple scattering and improve image contrast in a dynamic scattering medium
10.1364/OL.42.002738 2017-07-07 We demonstrate that complex decorrelation averaging can reduce the effect of multiple scattering and improve optical coherence tomography (OCT) imaging contrast. Complex decorrelation averaging calculates the product of an A-scan and the complex conjugate of ... |

Silicon microring modulator-based RF mixer for millimeter-wave phase-coded signal generation
10.1364/OL.42.002742 2017-07-07 Phase-coded radio frequency (RF) pulses are widely adopted for radar systems as an effective signal format to enable high-range resolution. However, generating such signals conventionally requires high-speed electronics and complex RF circuitry that impose bu... |

Real-time online photonic random number generation
10.1364/OL.42.002699 2017-07-06 We present a real-time scheme for ultrafast random number (RN) extraction from a broadband photonic entropy source. Ultralow jitter mode-locked pulses are used to sample the stochastic intensity fluctuations of the entropy source in the optical domain. A disc... |

Coherent field transients below 15 THz from phase-matched difference frequency generation in 4H-SiC
10.1364/OL.42.002687 2017-07-05 We experimentally demonstrate tunable, phase-matched difference frequency generation covering the spectral region below 15 THz using 4H-SiC as a nonlinear crystal. This material combines a non-centrosymmetric lattice and strong birefringence with broadband tr... |
