A PANDA ring resonator circuit has been applied to the measurement of muscle actions, measuring signals created by facial muscle contractions. A system, which is called the Optical Muscle Sensing System, was developed which uses sensors to measure the mechanism of facial muscle contractions and the strength of contraction and degrees of perturbation of the facial muscles that are used directly for each facial gesture. The signal data was obtained from the simulation of the facial gestures and this data was applied in the classification of the facial gesture signals of each particular gesture. Facial gestures include blinking, smiling, grimacing and various other contortions of the face which may imply emotions and are part of normal human communication. Understanding of these mechanisms will be useful and applicable to facial rehabilitation services.

We propose a micro-optical sensing system for muscle contraction and movement measurement, in which a PANDA ring resonator type is used as a basic optical device called Muscle Optical Sensor (MOS) system. The MOS system consists of an optical add/drop filter which is connected to two micro-ring resonators, of which the right ring is a sensing unit and the left ring is a reference ring. The key contribution of this paper is a novel approach for measuring contraction and transfiguration of muscles by using the small scale optical device. The contraction or transfiguration of muscle is directly perturbed into the sensing unit, which changes the optical path length. These resultant changes in wavelength (∆λ) are measured and obtained by the difference of the sensing and reference signals. The experiment was conducted by using the MATLAB and Opti-wave programs, which indicated that the changes in the sensing radius were associated with the change in wavelength. The results and techniques can be used beneficially for muscle sensing applications. 

One of the critical problems in achieving a real practical all-optical switching devices is the requirement for a strong material nonlinearity. A strong material nonlinearity is crucial in order to achieve a low switching power. However, silicon-based all-optical switches require extremely high switching power due to its relatively weak nonlinear optical properties. To overcome this limitation, we have designed an all-optical switch configuration based on silicon microring resonator structure and demonstrated the switching operation based on the nonlinear effects induced by a soliton pulse. The soliton pulse induces freecarrier concentration through two-photon absorption (TPA) effect and this leads to enhance the refractive index change and enhance the nonlinearity of the silicon. Thus, the silicon microring resonator alters the nonlinear phase shift which is required for switching.
