TLDR
In this article, a strain induced long period grating (LPG) was created by bonding an etched single mode fiber (SMF) onto a corrugated Si fixture with on-chip heater and temperature sensor.Abstract:
In summary, we report a strain induced long period grating (LPG) created by bonding an etched single mode fibre (SMF) onto a corrugated Si fixture with on-chip heater and temperature sensor. The loss of the LPG can be tuned electrically through the microheater current and monitored simultaneously. The use of Si fixture lends itself to easy integration of microheater and other cascaded filter structure. The results may be useful for dynamic spectral shaping in DWDM networks.read more

Min-Suk Kwon,Sang-Yung Shin +1 more
TL;DR: In this article, the feasibility of a polymer waveguide notch filter using a thermooptic long-period grating is demonstrated experimentally, and the attenuation of the filter is controlled by adjusting the power applied to the periodic heaters.
