Abstract
A wave-guiding system and method for mode-selective transmission of a spatially coherent light beam is disclosed. The system comprises a wave-guide with an inlet and an outlet for transmitting one or more modes; a first mode-shaping optical element for shaping the spatially coherent light beam before it enters through the inlet of the wave-guide to a desired mode of the wave-guide; and a second mode-shaping optical element for shaping light beam after it exits from the outlet of the wave-guide for obtaining a desired vectorial field.

A wave-guiding system for mode-selective transmission of a spatially coherent light beam, the system comprising:
- a wave-guide with an inlet and an outlet for transmitting one or more modes;
- a first mode-shaping optical element comprising a Pancharatnam-Berry Optical Element (PBOE) for shaping the spatially coherent light beam before it enters through the inlet of the wave-guide to a desired mode of the wave-guide;
- and
- a second mode-shaping optical element for shaping light beam after it exits from the outlet of the wave-guide for obtaining a desired vectorial field.
A method for mode-selective transmission of a spatially coherent light beam, the method comprising:
- mode-shaping the spatially coherent light beam to a desired mode of a wave-guide using a Pancharatnam-Berry Optical Element (PBOE);
- passing the light-beam with the desired mode through the wave-guide;
- and
- mode-shaping the light beam after it exits from the wave-guide for obtaining a desired vectorial field.
