LOW OPTICAL OVERLAP MODE (LOOM) WAVEGUIDING SYSTEM AND METHOD OF MAKING SAME

摘要

An optical system including: A substrate having a recess (30); and, a substantially planar, semiconducting waveguiding membrane (40) suspended over the recess and having a thickness less than about 200 nm; wherein, the optical system supports a propagating optical mode having a majority of its energy external to the semicoductor waveguiding membrane.
