We demonstrated a new type of integrated photonic waveguides formed by Ge ion implantation in the silicon slab on silicon-on-insulator platform. They were successfully fabricated and characterised, and can be potentially erased by laser annealing.

We have demonstrated a passively mode-locked erbium-doped fiber laser using colloidal PbS quantum dots (QDs) thin film as saturable absorbers (SAs). As the pump power up to 34.1 mW, we can observe the mode-locked pulse with the duration of2.86 ns.

Ultrasound assisted hybrid technique for optical imaging being available for biomedical tomography is proposed. Ultrasonic tagging on chemiluminescence (CL), which is derived by sonochemical effect of CL reaction, is applied for CL imaging in light scattering media. We have developed a tomographic imaging system equipped with an ultrasound phased-array transducer for electronic scanning of the ultrasound focus. The imaging performance using a body phantom including a luminol CL target was demonstrated, suggesting the potential for tomographic imaging of biological function with mm resolution in living bodies.

We present a study of compression of optical pulses using a free-space angular-chirp enhanced delay (FACED) cavity. The amount of induced dispersion can be adjusted by simply modifying the geometry of the FACED cavity.
