Cavity-enhanced narrowband spectral filters using rare-earth ions doped in thin-film lithium niobate
Abstract On-chip optical filters are fundamental components in optical signal processing. While rare-earth ion-doped crystals offer ultra-narrow optical filtering via spectral hole burning, their applications have primarily been limited to those using bulk crystals, restricting their utility. In thi...
