A 1.2-Mpixel indirect time-of-flight (ToF) CMOS image sensor is presented to lower peak current and to cancel out multi-user interference. The proposed 4-tap 3.5- $\mu \text{m}$ demodulation pixel is optimally designed to improve quantum efficiency (

We propose an injection locked triple contact Fabry–Perot laser diode (TC F–P LD) for an uncooled wavelength division multiplexing systems. By controlling injection currents to three electrodes of the TC F–P LD, we are able to tune the cavity m

We investigate feed forward noise suppression for ASE-seeded WDM systems in relation to its limitations. In particular, limitation factors such as background ASE of reflective light sources and filtering effect are thoroughly investigated. We also me

We propose an injection locked triple contact TC F-P LD for uncooled WDM system. Thanks to the mode tuning characteristics of TC F-P LD, we can optimize the detuning without using temperature control. We checked the quality of the output, and estimat

We investigate reduction of mode partition noise of a spectrally sliced Fabry-Perot laser diode (FP-LD) for application to seeded DWDM systems. The proposed scheme for the noise reduction incorporates a fiber-based Mach-Zehnder interferometer (MZI) a

We propose and demonstrate a reduction of mode partition noise of an F-P LD using a fiber-based Mach-Zehnder interferometer (MZI). Injection-locked dual F-P LDs suppress polarization dependence to reduce a noise power by 3-dB.

We demonstrate cost-effective 10-Gb/s broadcast signal transmission for WDM-PON employing mutually injected F-P LDs. The interferometric noise suppression technique improves transmission performance by eliminating the fundamental periodic noise peak.
