We have explored the possibility of using Transistor Laser as an Optical Amplifier in addition to its normal function as an electronic amplifier. The steady state gain is calculated by assuming different InGaAs Quantum Well thickness within the GaAs base of fixed width thereby changing the capture rate and confinement factor. Clear gin saturation effect is exhibited. Using ODE solver, the gain saturation as a function of time is demonstrated. The linewidth enhancement factor of the amplifier is also evaluated. ©2009 IEEE.

University of Calcutta (informally known as Calcutta University or CU) is a collegiate public state university located in Kolkata, West Bengal, India.&nbsp;Within India it is recognized as a &quot;Five-Star University&quot; and accredited &quot;A&quot; Grade by National Assessment and Accreditation Council.

&nbsp;

The University of Calcutta has secured the Fifth position among the Universities of India in the prestigious &quot;Indian University Ranking 2019&quot; list, released by the NIRF of the Ministry of Human Resource Development, Government of India.

&nbsp;

It was established on 24 January 1857, and was one of the first institutions in Asia to be established as a multidisciplinary and Western-style university. Its alumni and faculty include several heads of state, heads of government, social reformers, prominent artists, only academy award winner and Dirac medal winner in India, many Fellows of the Royal Society and five Nobel laureates as of 2019 which is highest in South Asia.
