Job Description

The PHO project (NRF funded) is looking for a Postdoc Researcher to conduct and analyse experiments aimed at understanding the experimental properties of a new type of hybrid optomechanical system: polaritonic drums.

PHO PROJECT

PHO: Polaritonic hybrid optomechanics

Polaritonic drums are a new design of micrometre-scale hybrid optomechanical system based on exciton-polariton resonances. This system is based on a semiconductor optical microcavity architecture, that involves a free-vibrating micro-mechanical oscillator that embeds an excitonic - bound electron hole pairs - continuum. This excitonic continuum is used as a strong mediator between the cavity photons and the oscillator motion and as a giant Kerr optical nonlinear medium. Owing to this unique combination of properties, the polaritonic drums are expected to exhibit a giant optomechanical interaction, that can be further amplified by a large amount, and that also opens up new measurement strategies.


In PHO all these properties will be tested, quantified experimentally, and confronted to theoretical prediction. The regime of high sensitivity, in which the force of a single photon is expected to be detectable, will be investigated by applying a non-classical radiation pressure on the system.

DESCRIPTION

The candidate will perform experimental optical micro-spectroscopy and mechanical radiofrequency spectroscopy, in cryogenic cooled polaritonic microcavities. He/she will participate in implementing and using the detection instruments, dedicated at optically exciting, detecting and characterizing the mechanical motion, and in preparing and calibrating the classical and quantum radiation pressure beam.


He/she will analyze the experiments and participate in the interpretation. He/she will participate in the theoretical discussion alongside the theory collaborators. The appointee will work in a highly collaborative environment and must feel comfortable in daily interactions with collaborators, live and remotely.

EXPERIENCE & QUALIFICATIONS

The candidate should have a solid academic track-record, and a previous experience in spectroscopy or optomechanics of micros-systems: like semiconductor nanostructures, quantum optical systems, ultracold atomic vapours etc...


The appointee will join Majulab at CQT (Singapore) under the supervision of Dr. Maxime Richard (Majulab & CQT affiliated, Singapore) and of Prof Alexander Ling (CQT principal investigator, Singapore). The project is located at the Centre for Quantum Technologies in Singapore.


The applicant should submit a detailed CV. Positions will initially be offered for 1 year, with possible extension. The start date is flexible. If shortlisted, applicants should also arrange for two letters of reference to be sent directly to the supervisors.

FURTHER INFORMATION & CONTACT

Salary range: 7000 to 10000 SGD (depending on suitability and experience)


Workplace address: The applicant will be a CNRS@CREATE appointee (CREATE Campus, CREATE Tower, 1 Create Way #08-01 Singapore 138602), and work full time at the Centre for Quantum Technologies (National University of Singapore) and Majulab, located at: CQT, 3 Science drive 2, 117543, Singapore.
