Post-doctoral fellow in Nonlinear optical Fiber Communication - 12 months contract

Who we are ?

Télécom Paris, part of the IMT (Institut Mines-Télécom) and a founding member of the Institut Polytechnique de Paris, is one of France's top 5 general engineering schools.

The mainspring of Télécom Paris is to train, imagine and undertake to design digital models, technologies and solutions for a society and economy that respect people and their environment.

We are looking for a Post-doctoral Fellow in Nonlinear optical Fiber Communication. You will join the COMELEC Department in GTO team. The Optical Telecommunications Group (GTO) is home to the research programs of six faculty members and a state-of-the-art laboratory on optical fiber transmission. We conduct advanced research in high-rate fiber-optic transmission, optical network architectures, advanced lasers for communications, integrated photonics, and distributed optical fiber sensors.

SCIENTIFIC CONTEXT

Optical fiber forms the backbone of the communication systems. The exponential increase in data traffic is putting an escalating pressure on fiber-optic networks. Optical fiber is a nonlinear medium because its properties change with the signal intensity. It is well known that the fiber nonlinearity limits the achievable information rates of the conventional transmission methods in optical communication. The problem of efficient communication over optical fiber channels is open, because the channels are governed by complex models that go beyond the standard models in communications.

The objective of this research project is to establish the information-theoretic limits in optical fiber, and to develop communication algorithms that approach these limits. The project uses neural networks to design receivers for the nonlinear optical fiber channel. The project is funded by an ERC Starting Grant from the European Research Council (ERC).

Your main tasks will be to :

• To carry out research missions in the field of Optical Fiber Transmission

• To ensure supervision and tutoring missions

• To contribute to the reputation of the School, the Institut Mines-Télécom and the Institut Polytechnique de Paris

The ideal candidate will have a PhD or equivalent in information and communication theory, signal processing, neural networks or physical applied mathematics (particularly in nonlinear dynamical systems). You have knowledge in fiber-optic transmission systems, neural networks and fiber nonlinearity

You are recognized for your ability to work in a team and for your interpersonal skills.

You are fluent in english.

Why join us?
You'll be working in a fast-growing, pleasant, green and accessible environment (especially for people with disabilities) just 20 km from Paris (RER B and C suburban train lines, close to major roads, shared shuttle departing from Porte d'Orléans). You will benefit from :

• 49 days annual leave (CA + RTT)

• flexible working hours (depending on department activity)

• telecommuting 1 to 3 days/week possible

• 75% public transport pass reimbursement

• Proximity to numerous sports facilities, concierge service, underground parking, in-house catering, etc.

• Staff association at school and ministry level

• Good to know: our social security contributions are lower than in the private sector
