Fronthaul data rates in case of millimeter wave (mmWave) wireless systems scale up to several Gbps in the currently deployed digitized radio over fiber solutions, resulting in large complexity remote radio heads (RRHs). We propose a promising solutio

This paper presents a diplexer design that generates a pair of fundamental and harmonic frequencies. The diplexer is based on a capacitively loaded resonator that is able to reconfigure its frequency pair with respect to capacitive loading. The syste

A high infrared-to-green conversion efficiency laser is demonstrated by extra-cavity frequency-doubling of a master oscillator power amplifier (MOPA) laser. The oscillator is a diode-side-pumped acousto-optic Q-switched Nd:YAG laser at 1064 nm with a

The mode mixing and mode dispersion in the multimode fiber (MMF) will produce complex speckle patterns in the distal end of the fiber as an object passes through the MMF, rendering image reconstruction to be a challenging task. In recent years, convo
