M. Watanabe et al., OBSERVATION OF SWITCHING RELATED TO BISTABILITY BETWEEN 2 CROSS-COUPLED LATERAL-MODES IN TWIN-STRIPE LASERS, IEEE journal of quantum electronics, 30(10), 1994, pp. 2232-2234
Switching between two cross-coupled lateral modes in gain-guided twin-
stripe lasers has been experimentally observed with current injection
of nominally identical pulses, which strongly indicates bistability. N
ear- and far-field patterns at both facets are presented, which clearl
y shows a skewed light field which couples from under one stripe to un
der the other. Cross-coupled mode operation was obtained only for rela
tively long cavity lasers, which is consistent with the theory for twi
n-stripe lasers with high interstripe gain.
