Abstract

We study a laser diode (cavity length L_d, facet reflectivities R_d) with a feedback provided by an empty external Fabry-Perot resonator (length L_r, mirror reflectivities R_r) at a distance L₀ from the laser diode. The characteristic lengths L_d, L_r and L₀ are associated with the roundtrip times τ_d, τ_r and τ₀, respectively. The external resonator is slightly tilted offaxis to avoid direct back-reflection and introduces an infinite number of delay terms into the evolution equation for the electric field.
