“…But due to the strong optical confinement by the total internal reflection, this device is suitable not for extracting high output power but for applications directly utilizing localized light. [9][10][11] In coupled cavity lasers, the switching between coupled modes takes place due to the gain switching. 5 The photonic molecule is an optical analog to chemical molecules; modal states similar to electron energy states are discussed for coupled resonators.…”

We demonstrate the bistable lasing in a photonic molecule consisting of twin microdisks. When the photonic molecule was nonuniformly photopumped, the bistability and/or mode switching were observed with an effective pump power of <100μW. The rate equation analysis indicated that the operation was based on saturable absorption and gain switching, which depended on the nonuniformity, disk diameter detuning, and Q factors of coupled modes. Such a bistable laser, particularly showing the mode switching, will be applied for ultrasmall high-speed optical memories, flip-flops, and so on.

Abstract-In this paper, we address the physical origin of self-pulsation in narrow stripe edge emitting semiconductor lasers. We present both experimental time-averaged polarization-resolved near-field measurements performed with a charged-coupled device camera and picosecond time resolved near-field measurements performed with a streak camera. These results demonstrate dynamic spatial-hole burning during pulse formation and evolution. We conclude from these experimental results that the dominant process which drives the self-pulsation in this type of laser diode is carrier induced effective refractive index change induced by the spatial-hole burning.

We report about theoretical results and experiments, which led to the demonstration of optical bistability on the specially modified laser diode (LD) created on the double heterostructure Ga 1-x Al x Al/GaAs with saturable absorption section. To prove the bistability, the time method for bistability impulse verification (BIV) by bistable laser diode (BLD) was proposed. With the use of the BIV method, basic parameters of the hysterisis loop of the W-A characteristic samples of realized BLD were determined. Also the mathematic model of the W-A characteristic was derived, used for the simulation of the characteristic for the realized BLD. Element values of the electrical equivalent circuit of the BLD for small changes of signal were calculated for selected operating points of the simulated W-A characteristics. The dependency of bistability on the temperature is monitored by measuring the BLD W-A characteristic.
