We demonstrate lasing in dual cavity photonic crystal VCSELs with independent control over injection currents, suggesting potential for advanced laser applications.
We demonstrate 940nm lasing operation in either the in-phase or out-of-phase coherent supermode from dual element photonic crystal surface emitting laser diode arrays. Either supermode can be selected through control of two independent injection currents up to 4mW output.
