We fabricate a tensile-strained InGaAsP-InP quantum-well (QW) laser with coupled two disks, emitting at 1.5μm. For a microdisk with radius of 10μm and a 2-μm-wide output waveguide, a continuous-wave (CW) threshold current is 24mA at room temperature and the mode intervals of 2 and 5.3nm are observed, corresponding to splitting of symmetric and asymmetric modes, and longitude mode space. The peak intensity of main mode is 25dB higher than the background with the wavelength of 1522nm at 115mA.

A novel fiber laser load sensor based on beat frequency demodulation technique is presented. When the load is applied on the sensor, the laser cavity will be stretched, which leads to the frequency shift of beat frequency signal. Thus, the load can be obtained by measuring the beat frequency. In the experiment, four different beat frequency signals are studied and compared in the load measurement. The sensitivities are -12.63kHz/kg, -27.80kHz/kg, -41.29kHz/kg, and -53.88kHz/kg, respectively. The paper proposes a cost-efficient scheme for load measurement.

We demonstrate optical bistability on a small SU-8 race-track-resonator with a Q-value as high as 30000, which helps to achieve nonlinear optical responses even at low operation power due to an enhancement of optical power density in the resonator. Significant thermal nonlinear optical effect in the fabricated SU-8 race-track-resonator is demonstrated experimentally, which is attributed to the high Q-value and the large negative thermo-optical coefficient.
