title: Strong resonance effect in a lossy medium-based optical cavity for angle robust spectrum filters.
abstract: Spectrum filters with a wide viewing angle exploiting strong resonance effects in lossy media are demonstrated. The designed filters show significantly improved color purity and the angle-robust characteristic can be preserved up to ±65° due to an interesting phase-cancellation effect. This strategy could provide new routes for numerous applications, such as image sensors and displays.
