In this paper, an offset QAM/OFDM combined with non-orthogonal multiple access (OQAM/OFDM-NOMA) modulation technique is proposed and experimentally demonstrated in a multi-user and asynchronous mul…
A sampling frequency offset (SFO)-robustness scheme with zero padding (ZP)-fast orthogonal frequency-division multiplexing (FOFDM) is proposed and experimentally demonstrated in intensity-modulated…
By incorporating of a combined mesa cleaning of SF 6 plasma bombarding and HCl rinsing prior to the SiN x passivation, an ultra-low dark current density of 9.1 nA/cm 2 at 180 K under a reverse bias…
Stability, robustness, sensitivity, and reproducibility are important parameters in the interferometry. We propose a wavefront splitting fiber Mach-Zehnder interferometer (MZI) to achieve such perf…
Ultra-low-loss all-fiber mode selective couplers (MSCs) have been designed and fabricated using fused biconical taper technique with precise control on phase matching condition. An LP 01 MSC with m…
An excitation source with two independent-tunable Stokes wavelengths is demonstrated for dual-frequency coherent anti-Stokes Raman scattering applications. Two Stokes wavelengths can be independent…
The spectroscopic properties of Er 3+ -doped tellurite glasses were investigated and a 1 wt.% Er 3+ -doped tellurite fiber was fabricated for L-band lasers. Wavelength-tunable fiber lasers in a lin…
Filtering images is required by numerous multimedia, computer vision and graphics tasks. Despite diverse goals of different tasks, making effective rules is key to the filtering performance. Linear…
