Tapered Fiber Fabrication
... confining the light into a small space. This increases the intensity of the field in the core of the fiber and results in more light being guided outside of the core. Then, light can be coupled into objects such as microresonators by means of frustrated total internal reflection. Tapered optical fib ...

Mode-locking
Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s).The basis of the technique is to induce a fixed-phase relationship between the longitudinal modes of the laser's resonant cavity. The laser is then said to be 'phase-locked' or 'mode-locked'. Interference between these modes causes the laser light to be produced as a train of pulses. Depending on the properties of the laser, these pulses may be of extremely brief duration, as short as a few femtoseconds.
