We have proposed a modified structure called the “charge focusing” design of a single-photon avalanche diode, based on our previous work using TSMC's 0.18 μm HV CMOS technology. We have demonstrated that this modified structure can improve the electric field distribution in the photon absorption layer, which previously resulted in worse jitter performance. This modification enhances carrier collec...Show More
Lighting communication is the ongoing development in human society for fulfilling the practical need of full-space network coverage with heterogeneous wired and wireless communication infrastructures. Light-emitting diodes (LEDs) and laser diodes (LDs) have been successfully introduced as the optical wireless communications data carrier. The latter reveals better data transmission performance owin...Show More

The multiple data formats such as the quadrature amplitude modulation-orthogonal frequency division multiplexing (QAM-OFDM), generalized frequency division multiplexing (GFDM), and discrete multi-tone (DMT) are discussed for the 850-nm multi-mode vertical-cavity surface-emitting laser (MM-VCSEL) based transmission in back-to-back (BtB) and OM5-multimode fiber (OM5-MMF) cases. The 850-nm MM-VCSEL w...Show More
Herein, a lucid meta-holographic approach leveraging geometric phase metasurfaces and photonic crystal surface-emitting lasers is presented. Such a straightforward technique inherently enables polarized structured light projection with opposite circular polarization states, effectively doubling the field of view for depth sensing applications. Furthermore, the innate polarization state of projecte...Show More

A novel single-photon differential phase-shift keying (DPSK) scheme with asymmetric high-bit-rate coding (at 192 Mbit/s) and low-bit-rate gating (1 Mbit/s) coding data format is proposed to stabilize the long-term and long-distant point-to-point secure communication over 40-km standard single-mode-fiber (SSMF).

Wavelength selective injection-locking of a 1545.59-/1548.18-nm dual-mode DFBLD with a transient-current-switched single-mode master DFBLD is performed for differential phase-shift-keying and delay-interferometric on-off-keying at 192 MHz that enables secure and complex quantum-key-distribution via alternative wavelength switching.Show More
