Bursting is a striking feature found in a wide range of physical and biological systems. It is characterized by periods of quiescence that are interspersed with periods of activity. We present an experimental and theoretical study of an interesting bursting mechanism in a two-mode semiconductor laser with single-mode optical injection. By tuning the strength and frequency of the injected light we...
Mode-locking at 100 GHz with 2 ps pulse duration is demonstrated in a quantum-well diode laser designed to support a discrete comb of modes. Spectral filtering was achieved using a non-periodic patterning of the cavity effective index.
An experimental study of multimode dynamics in a two-mode semiconductor laser with optical injection is presented. The device we consider is a specially engineered two-colour Fabry-Perot laser diode [Eblana Photonics] with a large (THz) primary mode spacing. At a fixed injected power level, we vary the detuning of the injected field from the long wavelength mode of the device. The optical spectra...
The semiconductor laser with an injected signal is a conceptually simple system which nevertheless displays complex dynamics including chaos. Experimental and theoretical studies of this system have tended to focus on single mode lasers. Using an inverse problem solution, which relates the threshold gain modulation in wavenumber space to the spatially varying refractive index in a Fabry-Perot (FP)...
A two-color Fabry-Perot laser is designed with a distribution of slots in the ridge waveguide, fabricated and characterised. The two-color lasing produces a strong four wave mixing signal, and is promising for direct THz emission.
A discrete mode Fabry-Perot laser is designed and fabricated to achieve two-color lasing. We demonstrate beating between the two laser modes and self-pulsation at 480 GHz.
We present two-colour Fabry-Perot lasers obtained using non-periodic effective index patterns. The devices oscillate simultaneously on two Fabry-Perot modes and are attractive for THz generation
