“…2021, 11, x FOR PEER REVIEW 2 of 16 crosstalk between channels, so the temperature of the device needs to be stabilized when applied to DWDM systems. However, for active temperature stabilization, the use of cooling devices such as heaters or Peltier Coolers requires power consumption and electronic control circuits, and issues such as price, device size, and reliability limit the widespread use of DWDM systems [17,18]. This study performed reliability and accelerated life tests on a 96-channel (50 GHzspacing) athermal AWG module fabricated by installing a temperature compensation board on the back of a silicon substrate.…”

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.
