|Title:||Behavior Of Spontaneous Emission Across Threshold In Gaas Junction Lasers|
|Abstract:||The spontaneous emission behavior of a cw stripe-geometry GaAs laser is examined in detail. Contrary to recently published results, a sharp discontinuity of the spontaneous emission growth occurs when the laser reaches threshold. Above threshold, slow increases in the spontaneous emission are observed, coming mostly from the regions where the lasing light intensity is small. Other discontinuity points were, at higher currents, observed corresponding to the onset of higher-order modes and second-order mode locking. © 1972 The American Institute of Physics.|
