Coexisting frequency combs spaced by an octave in a monolithic quantum cascade laser
Andres Forrer, Markus Roesch, Matthew Singleton +3
Quantum cascade lasers are proving to be instrumental in the development of compact frequency comb sources at mid-infrared and terahertz frequencies. Here we demonstrate a heteroge…

Evidence of Linear Chirp in Mid-Infrared Quantum Cascade Lasers
Matthew Singleton, Pierre Jouy, Mattias Beck +1
We measure the inter-modal phase relation of a quantum cascade laser frequency comb operating at 8 um using a coherent beatnote spectroscopy. We find these phases to be reproducibl…
