On-chip green laser sources are essential for integrated photonic circuits and quantum technologies, particularly to address the “green gap” in semiconductor lasers [1]. Frequency-conversion-based green light generation methods such as third-harmonic generation, optical parametric oscillation, and second-harmonic generation (SHG), have shown great progress in the last few years, although the output power is still limited mainly due to low efficiency or low damage threshold.

Abstract
On-chip green laser sources are essential for integrated photonic circuits and quantum technologies, particularly to address the “green gap” in semiconductor lasers [1]. Frequency-conversion-based green light generation methods such as third-harmonic generation, optical parametric oscillation, and second-harmonic generation (SHG), have shown great progress in the last few years, although the output power is still limited mainly due to low efficiency or low damage threshold.File in questo prodotto:
