Abstract :
Leakage current in quantum-cascade-lasers with oxide-blocked-ridge waveguide and buried-heterostructure (with/without n-InP top-cover) are compared using electrical derivative measurements. Oxide-blocking structure provides the least leakage current although the top-covered BH QCLs show the toughest durability.
