# Design and Characterisation of Multi-Mode Interference Reflector Lasers for Integrated Photonics: Data

In this work, we describe the modelling and design, fabrication and characterization of MMIR lasers based on InAs QDs grown on GaAs. The simulation data is based on GaAs / InAs QD laser with a deep etched waveguide. The simulated 1×2-port MMI was designed for a layer stack with an effective index of 3.3, as shown in Figure 3 (a). All numerical data are included in as flowing: simulations data, Ith data, and wavelength data, which are the data shown in each corresponding section.

In the simulation data file. Excel type, there are four sub sheets:

- "fig.3 b", corresponding to figure 3 (b) data, is seven columns showing the MMI output power vs MMI length by using Fimmwave (EME), the power in fimmwave is normalized to 1, the last two columns show the fundamental TE00 mode power in (%).
- "Fig.4 a" corresponding to figure 4 (a) data, includes the data of simulating the MMIR by dividing it into two parts and applying the EME by Fimmwave and then field stored and launched into OmniSim (a Finite Difference Time Domain (FTTD) model) as represented in Figure 2. The reflectivity is calculated by using equation (1)
- "Fig.4 b" is the OmniSim calculation for mirror angle vs TE00 reflectivity.
- "Fig.5 d" is the total reflectivity for TE00, TE01, and TE02

In the current data file. Excel type is three sub sheet:

- "Fig.7 a" is the I-P data for FP and MMIR laser with cavity lengths 0.5- and 1-mm cavity length which is in figure 7 (a)
- "Fig.7 b" is the I-P data in temperature depend for FP and MMIR laser with 1 mm cavity length, which is in figure 7 (b)
- "Fig.8" is the current density data for FP and MMIR for cavity lengths 0.5, 1, 2, and 3 mm.

In the Wavelength data file. Excel type, there are four sub sheets:

- "Fig.9" Peak lasing wavelength for FP and MMIR lasers for cavity lengths 0.5, 1, 2, and 3 mm.
- "Fig.10 a", "Fig.10 b", and "Fig.10 c" is the lasing spectrum measurement using an optical spectrometer for 0.5 mm cavity length MMIR in "Fig.10 a", and in "Fig.10 b" and "Fig.10 c" is FP laser for 0.5 and 1 mm cavity length, at 20 and 45
^{o}C.
