Resonance-free optical frequency response with -3 dB bandwidth of more than 26 GHz has been achieved for a single quantum well transistor laser by using graded index layers of AlξGa1-ξAs (ξ: 0.1→0) in the left side of quantum well and AlξGa1-ξAs (ξ: 0.05→0) in the right side of quantum well. All required parameters, including quantum well and base transit time, optical confinement factor and spontaneous recombination lifetime, have been calculated using a self-consistent charge control model.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {17}, number = {12}, year = {2023}, pages = {159 - 162}, ee = {https://publications.waset.org/pdf/10013425}, url = {https://publications.waset.org/vol/204}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 204, 2023}, }
