3D laser technology is widely used to collocate the surface information of object. For various applications, we need to extract a good perceptual quality point cloud from the scanned points. To solve ...
CMOS image sensor designers take advantage of technology scaling either by reducing pixel size or by adding more transistors to the pixel. In both cases, the distance from the chip surface to the phot...
Diffractive diffusers (phase gratings) are routinely used for homogenizing and beam shaping for laser beam applications. Another use for diffractive diffusers is in the reduction of speckle for pico-p...
The field sequential color (FSC) mechanism can effectively generate multi-primary color fields in temporal sequence to form a full-color image. Color breakup (CBU), however,has appeared intrinsically ...
Field-sequential color (FSC) is a high optical throughput technique for future green liquid crystal displays (LCDs). However, the FSC-LCD faces a lethal issue, color breakup (CBU) which degrades image...
A novel micro-grooved structure of lightguides and a sequential driving scheme of light soures were demonstrated in achieving comparable image qualities of 3-D displays to that of 2-D displays. The mo...
High-speed all-optical data-format conversion and logic gate from a synchronously modulated Fabry朠閞ot laser diode (FPLD) below threshold condition is demonstrated by using external injection-induced n...
We present a hybrid silicon evanescent laser that uses poly-silicon thermal shunts to reduce the device thermal impedance from 41.5 to 33.5 deg. C/W.
Trench-assisted multi-core fiber (TA-MCF) is proposed to achieve high dense MCF design with a solid structure. The crosstalk value at 1.55 μm of fabricated TA-MCF is estimated to be –35 dB at 100 km.
We proposed a novel method to implement the coherent seeding source using optical feedback and experimentally demonstrated the feasibility of our seed light under various back reflection levels in a l...
We develop network design algorithms that consider constraints on the number of added/dropped optical paths at nodes in terms of wavelength and of fiber. The strategy is demonstrated to significantly ...
The timing and optical laser phase of individual bands in multi-band OFDM are correlated. We significantly reduce the OFDM overhead through using FFT window synchronization for channel estimation and ...
Fast SOP changes in fiber-based dispersion slope compensating modules (DSCMs) due to mechanical impact are effectively suppressed by introducing a simple passive vibration-suppression scheme consistin...
Power-conversion efficiency reduction on a quasi-homogeneous solid multi-core fiber is numerically investigated. The fiber length dependence of measured crosstalk of fabricated fibers is in good agree...
To reduce the MAI noises from the received OCDM signals, a new electrical time gating method has been designed and evaluated. The results show a bit-error rate improvement of up to over 10 8 .
