Models of thermally-induced mode instability, taking the backward reflection into consideration, has been derived, and influence of backward reflection on thermally-induced mode instability has been studied numerically for the first time. Numerical results reveal that one percent of backward reflection can result in 33% reduction of mode instability threshold.
