Abstract
In this work, we investigate non-contact tuning methods to re-align a beam of light in an optical circuit. We show that by combining flexures and femtosecond laser based exposure at low energy pulses, optical elements (a mirror in this case) can be repositioned remotely in a reversible manner, permanently and with unprecedented levels of accuracy down to sub-micro-radian levels. Due to the monolithic nature of these elements and our non-contact tuning approach, they occupy considerably less space and thus offer new possibilities in device miniaturization. Additionally, we show that such repositioning is permanent in nature – meaning – once the device is exposed to the laser and the optimal position is found, it does not fluctuate away from that position.
