Atomic-ensemble-mediated modulation of optomechanical properties in a Laguerre-Gaussian rovibrational cavity

Key Points

• The aim is to investigate the optomechanical properties of a Laguerre-Gaussian cavity system with atomic ensembles.
• Solve the Heisenberg-Langevin equations.
• Analyze the coupling between the cavity field and atomic ensemble.
• Investigate the effects of varying atomic numbers and pumping field power.
• Examine the influence of cavity decay rates on the absorption spectrum.
• Adjust the topological charge of the cavity mode.
• Coexistence of OMIT and EIT windows in the absorption spectrum due to coupling effects.
• Adjusting the atomic number influences the depth and width of the EIT and OMIT windows.
• Modification of the cavity decay rate allows control over the peak intensity in the absorption spectrum.
• Tuning the effective detuning enables asymmetric multiple Fano resonances in the absorption spectrum.
• Dynamic control over output field energy among transmission, reflection, and absorption pathways.
