| Research Abstract |
We fabricated an optical rotator that is confined in a microcavity inside a glass substrate, and rotated it by an non-contact technique of optical tweezers. The fabrication technique used consists of two steps :{ micro modification by focused femtosecond laser pulses} and{ selective etching of the modified region}. This is a unique technique that enables us to carry out a removal processing inside transparent solid substrate with a micro-meter resolution. In the present, study we developed such fabrication and rotation techniques.
