Fig. 3: Advantageous properties of MOD.
From: 3D ultra-broadband optically dispersive microregions in lithium niobate
a Schematic of MOD patterning with laser incidence oriented perpendicularly to the optical axis of LiNbO3. b Monochromatic and multi-color butterfly patterns produced by using MOD patterning. c MOD signals obtained in transmission mode and reflection mode. Insets: spectral properties of the marked points in the dispersive microregion. d Viewing angle independence of MOD verified by characterizing MOD signals under different magnifications. e Stability of MOD elements under harsh conditions, including high temperature, contamination, corrosion, and mechanical damage. For experimental conditions and stability assessments, see methods. f Universality of the MOD approach in different birefringent crystals.
