Abstract
Abstract
In the current work, a novel benzothiazole waveguide polymer
consisting of azo chromophore molecule
2 -[4'-(N, N-hydroxyethyl)-amino-phenyl azo]-6-nitrobenzothiazole
(HEPNBT) was prepared for the simulation of thermo-optic switch at the
infrared communication wavelength 1.55 μm. The
thermal property of ABHEPU was measured using the differential
scanning calorimeter (DSC) and thermal gravimetric analysis (TGA). The
glass transition temperature (T
g
) and decomposition temperature
(T
d
) at 5% mass loss are 110 ℃ and
266 ℃, respectively. The refractive indices of
ABHEPU waveguide polymer were determined at different wavelength
(532 nm, 650 nm or 850 nm) and
temperature using attenuated total reflection (ATR) technique. The
transmission loss, dispersion curves and Sellmyer coefficients of
ABHEPU polymer were investigated from CCD digital imaging devices and
Sellmyer equation, respectively. Polymeric 1 × 2 and
Mach–Zehnder interferometer (MZI) thermo-optic switches based on the
ABHEPU as waveguide material at the infrared communication wavelength
1.55 μm were designed and simulated. Simulation
results with FD-BPM method showed that the power consumption of
1 × 2 thermo-optic switch is only 0.58 mW; and the
response times of 1 × 2 and MZI switches are 12 ms
and 3.0 ms for the designed device. The switching time of
the prepared ABHEPU polymer is much shorter than that of silica
substrate.
