Area of Science:

Quantum Information Science
Optoelectronics
Materials Science

Background:

Efficient single photon sources are crucial for quantum information science.
Existing sources often lack tunability or high collection efficiency.

Purpose of the Study:

To develop an efficient and tunable single photon source.
To investigate the impact of spectral tuning on photon collection efficiency and decay rates.

Main Methods:

Integration of an Indium Arsenide (InAs) quantum dot (QD) within a photonic crystal cavity.
Coupling the cavity to a highly curved microfiber (μ-fibre) for evanescent coupling.
Tuning the spectral resonance by adjusting the μ-fibre contact position.

Main Results:

Achieved a high photon collection efficiency of 23%.
Observed Purcell-enhanced spontaneous emission from the quantum dot.
Demonstrated spectral tunability of the cavity resonance by up to 1.5 nm.
Systematically studied collection efficiency and decay rates versus quantum dot-cavity detuning.

Conclusions:

The developed system offers an efficient and tunable single photon source.
Evanescent coupling via microfiber provides high collection efficiency.
Tunability enhances spectral coupling probability, crucial for quantum applications.
