- Abstract
- We have developed a 17-channel (150 GHz-spacing) athermal arrayed waveguide grating (AAWG), which has a wider operation range than that of the existing AWGs, by designing a metal structure assembly that reduces the temperature dependence of the wavelength. For an operation temperature range from ?닋40 °C to 85 °C, the center wavelengths of all channels had a wavelength stability of 짹0.04 nm and the insertion loss variation was less than 짹0.78 dB. The accelerated life test showed that the predicted service life was expected to be more than 41.7 years.
