LD08–Thermally-Enabled Transmission Line Laser Model with Arbitrary Sampled Gain Spectra

In this paper we demonstrate a directly coupled opto-electro-thermal (OET) transmission line laser model (TLLM) for edge emitting laser simulations and its comparison to physical simulations and measurements. Our results show that the OET TLLM has comparable computational efficiency to the standard opto-electronic (OE) TLLM and can include self-heating effects with good accuracy. As such OET TLLM can be used as a flexible tool for reduced order physical modeling, as well as for photonic integrated circuit (PIC) simulation, including thermal and external feedback effects.
