We report real-time imaging and dynamics monitoring of micrometer predefined and random sized particles by time–space-wavelength mapping technology using a single-detector. Experimentally, we demonstrate real-time line imaging of a 5 μm polystyren

We demonstrate dual-wavelength short pulses lasing at 1540 and 1675 nm based on a silicon waveguide. The inline silicon waveguide inside a laser cavity facilitates pulse compression and laser mode-locking due to two-photon absorption (TPA) and TPA-in

Width-modulated silicon waveguide is investigated as a means of quasi-phase-matching to enhance the bandwidth of wavelength conversion based on four-wave-mixing. A conversion bandwidth enhancement of ~40% is achievable in a 5mm sinusoidally modulated

With a transparency window up to 6 μm, sapphire can serve as a platform to support silicon photonic integrated circuit in MWIR. Planar waveguide devices based on silicon-on-sapphire (SOS) are emerging as a bridge between MWIR and SWIR through freque

Four-wave mixing (FWM) in silicon waveguides is considered to be a promising effect to realize the wavelength conversion function for wavelength-division-multiplexing optical communication systems. Compared to the degenerate FWM with a single pump, t

In this study, we demonstrate method for quasi phase matched silicon-on-sapphire waveguides suitable for MWIR wavelength conversion to achieve higher conversion efficiency than that can be achieved in uniform waveguide geometries. In particular we sh

We investigate synchronous first and second order pulsed Raman lasers that can achieve frequency spacing of up to 1000 cm−1 for CARS microscopy applications. In particular, we focus on analytical and numerical analysis of pulsed stability derived f

We analyzed the noise performance of time stretched analog to digital converter with both lumped and distributed amplification cases. We show that distributed amplification provides up to 16dB higher SNR corresponding to ∼2.5 bit higher resolution.
