“…Так, чтобы вызвать сдвиг длины волны брэгговского резонанса на 1,5 нм, потребуется изменение температуры примерно на 120 K. При работе датчика в условиях относительно постоянных температур (например, в морской воде) это несущественно, а там, где это необходимо, можно применить специальные способы пассивной термокомпенсации ВБР, предложенные в работах [9,10].…”

“…LPFG can be used as wavelength division multiplexing (WDM) isolation filter [2], dispersion compensators, gain flattening filters and band rejection filters. LPFG has demonstrated a wide range of applications both in optical communication such as gain equalizers, band pass filters [3], polarizer, and in sensing elements and sensing demodulators [4].…”

“…The temperature-sensitive of LPFG is the disadvantage when be used for the purpose of the wavelength stability. To solve the problem, an approach using negative strain coefficient of LPFG was alternative [1,4,5]. This approach did not need any active temperature control and was simple, reliable.…”

A passive temperature-compensating package of Long Period Fiber Grating (LPFG) was designed based on its negative strain coefficient. LPFG was pasted on the substrate material, such as copper and Plexiglas, under tension. The strain induced by the thermal expansion of substrate material was used for temperature compensating .The experimental results showed that the mounted grating on copper exhibited lower temperature sensitivity (about 78pm/°C), compared with uncompensated grating(about 118pm/°C). But the transmission spectrum waveform of the mounted grating on Plexiglas changed. It was demonstrated that this package could improve the wavelength stability of LPFG when appropriated substrate material was chosen.

In this paper, we have proposed a principle to design a compact and temperature independent electro-optic switch based on a slotted photonic crystal directional coupler (SPCDC). Infiltration of the slotted silicon photonic crystal with polymer enhances the slow light and decreases the switching length, whereas the different signs of thermo-optic coefficients of the polymer and silicon make the proposed switch stable within 25℃ to 85℃ temperature range. The SPCDC structure is modified to increase poling efficiency of the polymer in the slot and to flatten the dispersion diagram of the even mode to minimize the switching length.
