Abstract :
In a ring laser gyroscope, due to
the rotation and the Sagnac effect, a phase
difference between the two counter-propagating
beams is generated. In this device, the higher
phase difference between these two beams
causes the better the interference pattern
detection, and thus the sensitivity is increased.
In this paper, the effect of inserting a dielectricgraphene
photonic crystal inside a ring laser
gyroscope on the interference pattern and the
sensitivity of the device are studied and
simulated using ABCD propagation matrix
method. Results show that dielectric-graphene
photonic crystal has a high transmission and
therefore high efficiency in the wavelength of
ring laser gyroscope. So it is a suitable choice to
use in the ring laser gyroscope. Also, a
comparison between ring laser gyroscope with
and without dielectric-graphene photonic
crystal shows that when the dielectric-graphene
photonic crystal is in the system it is possible to
build gyroscope with smaller lengths and high
sensitivity.
