Temperature Insensitive New Super Athermal AWG with Extreme Low Wavelength Drift
Mar. 06, 2023
POINTek, Inc., a global leader and provider of high performance athermal AWGs (AAWGs) and optical module packaging services, today announced the release of the New Super AAWGs significantly improving the Thermal Wavelength Insensitivity over the -40°C ~ 85°C industrial temperature environment.
Conventional athermal AWGs are made to support a total of 60pm or larger wavelength drift, which amounts to compensating 0.5pm/°C shift in the AAWG operating temperature range of -40°C to 85°C. In POINTek's New Super AAWG which is based on IP-pending optical packaging technology, the New Super AAWGs can support a total of typical 15pm or less wavelength drift, equivalent to 0.12pm/°C shift in the -40°C to 85°C range. Therefore, the New Super AAWG can sufficiently withstand any OSP applications such as 5G wireless fronthaul deployment. Also, the New Super AAWG provides the much-enhanced thermal wavelength insensitivity for the ISP applications. This New Super AAWGs can support a total of typical 5pm or less wavelength drift, equivalent to 0.07pm/°C shift in the operating temperature range of 0°C to 70°C whereas even well-made conventional AAWGs perform total of 20pm or larger wavelength drift or 0.3pm/°C shift in the 0°C to 70°C range (see the following comparison figures at the industrial (Figure 1) and standard temperature (Figure 2) ranges below).
