| Project Description | 
Very High Data rate Wireless Home Area Network concept based
on an optical distribution infrastructure and radio over fibre. |
Teldot Context
The drastic increase of the internet traffic requires the development of high bandwidth high bit rate optical
networks.
Teldot Objectives
to fully exploit all the potential of Quantum Dot (QD) based Mode-Locked Lasers (MLLs) as novel
laser sources offering cost-effective solutions for access and metro networks. |
Teldot objectives details:
- Development of low noise:
- QD based MLLs for multi-wavelength (16-32 channels) comb generation at 1.3
µm and 1.55 µm compatible with 10 Gbit/s transmission.
- 60 GHz QDot based
Mode-locked lasers for novel, radio over fiber (wireless systems). This implies specific QD material
engineering and optimization to achieve a highly sufficient modal gain together with broad optical emission
spectrum that can accommodate over 16 ITU channels, 100 GHz spaced.
For the second application, a
photonic integrated circuit (PIC) consisting of MLL, Bragg grating and optical amplifier will be developed for
increased functionality and performances.
- Implementation of these novel sources in test-beds at the
telecom partner (FT-Orange) and academic ones:
- Fiber To The Home: WDM passive optical networks and metro networks using comb-generators
- Radio over fiber at multigigabit signals (1-10 Gbps)
