“…Mobile data speed increased from 200 kbps to several Gbps with the transition from 3G over LTE and LTE-A to 5G, and the number of users, antennas, and base stations is increasing exponentially [1]. Low-power multi-channel photonic integrated devices are promising candidates to address the increasing energy consumption and bandwidth demands faced by network operators, and enable efficient deployment of wavelength division multiplexing (WDM) in next-generation passive optical networks (PON) [2,3]. DWDM (dense wavelength division multiplexing) [4][5][6][7] has expanded from longdistance transmission systems to large cities and access networks for many years to meet the rapid advancement, diversification, acceleration, and the large-capacity of communication services based on Internet technologies.…”

A 96-channel (50 GHz-spacing) athermal AWG has been developed. It has a wide operating range due to reduced temperature dependence than conventional AWG. The temperature dependence of the center wavelength of the developed module satisfied the ±0.05 nm range in all channels in the temperature range of −40 °C to 85 °C, and the insertion loss variation was also less than ±0.5 dB. As a result of validating its reliability through tests based on Telcordia-GR-1209 and GR-1221, the temperature dependence of the center wavelength satisfied the ±0.022 nm range, and the insertion loss variation was also less than ±0.2 dB. Accelerated life testing showed an expected service life of over 36.7 years, ensuring long-term safety of communication quality in harsh indoor and outdoor environments.
