Optical interference arrangement for coupling electromagnetic radiation into e.g. three-dimensional photonic crystal, has coupling structure aligned so that field inputs are brought into interference in predefined interference sample

摘要

The arrangement has a coupling structure (2) to which multiple electromagnetic radiation fields are separately guided. The coupling structure is formed, arranged and aligned such that multiple electromagnetic field inputs (4a-4b) are brought into interference in a predefined interference sample (5) by the coupling structure in an inflow area (3) of a photonic crystal or quasi-crystal (1). The inflow area is arranged at a surface and/or in interior of the photonic crystal or quasi-crystal. Independent claims are also included for the following: (1) a method for manufacturing an optical interference arrangement (2) a method for coupling electromagnetic radiation into photonic crystal or a quasi-crystal.
