Numerous researchers have studied innovations in future sixth-generation (6G) wireless communications. Indeed, a critical issue that has emerged is to contend with society's insatiable demand for h…
We have developed a compact 4 × 80-Gbps transmitter-receiver optical subassembly (TROSA) module using a chip-to-chip optical butt-coupling method. For a Tx submodule, four directly modulated laser…
Increasing mobile traffic and smart devices require continuous expansion of optical access network capacity and easy optical connectivity for residential, business, and mobile services. A high-spee…
We have investigated the transverse-mode behavior of 850 nm VCSELs using time-average lasing spectra and eye patterns. Measurements were done at varying DC bias currents, bitrates, and modulation a…
