Passive microring-resonator-coupled lasers
نویسندگان
چکیده
In this letter, a passive microring-resonator-coupled semiconductor laser structure is proposed. The weakly coupled high-Q microring resonator provides a strong mode-selection filter and could considerably extend the effective cavity length of a conventional Fabry–Perot laser. The side-mode suppression ratio, the linewidth and the frequency chirp of this laser are dramatically improved comparing to distributed feedback and distributed Bragg reflector lasers. © 2001 American Institute of Physics. @DOI: 10.1063/1.1420585#

Single-Mode Lasing Operation Using a Microring Resonator as a Wavelength Selector
We have demonstrated semiconductor lasers with microring resonators as frequency-selective elements. We show that the small resonator inside the laser makes single frequency-mode operation possible with reasonably good side-mode rejection.

We experimentally demonstrate single longitudinal mode operation in microring laser using the concept of PT symmetry. A PT-symmetric coupled resonator arrangement can considerably enhance the maximum achievable gain of single mode microring cavity. The method is broadband thus work well for inhomogenously broadened gain mediums. It doesn’t rely on any additional component to ensure its mode sel...
متن کاملImproved optical filter responses in cascaded InGaAsP/InP microdisk resonators
Waveguide-coupled microdisk and microring resonators as optical filters have been of great interest due to their high wavelength selectivity and ultra-compact sizes [1 – 4]. Recently, higher-order filters based on microring resonators with improved performances have been demonstrated in compound glass and AlGaAs/GaAs material systems [3, 4]. These higher-order filters show steeper rolloffs and ...
متن کاملDynamics of two semiconductor lasers coupled by a passive resonator.
The stability of two semiconductor lasers that are spatially separated by a passive resonator is analyzed using the composite-cavity mode approach. We study the nonlinear interactions of three composite-cavity modes and identify regions of in-phase and out-of-phase laser locking in the parameter plane of the transmission coefficients of the coupling mirrors and the laser length difference. Bifu...
متن کاملInP-Based Passive Ring-Resonator-Coupled Lasers
Design of passive ring-coupled lasers based on InGaAsP waveguides is investigated using beam propagation method. Mode coupling, propagation loss due to bending, and scattering loss from waveguide sidewall roughness are taken into account. By compromising threshold gain, linewidth and side-mode suppression ratio (SMSR), suitable waveguide width and coupling strength are determined for different ...
