Research Interest

Photonic TransmissionThe Photonics Transmission Cluster (PTC) at TM R&D is under the Photonics Technology Programme which, in turn, is one of the programmes under the Basic Research Department. Other clusters under the Photonics Technology Program led by Mr. Romli Mohamad are The Photonics Network Cluster (PNC) and The Photonics Devices Cluster (PDC). The photonics work also extends to advanced communication system concepts, including coherent detection in single-mode fiber, spatial multiplexing in multi-mode fiber, and free-space links. The current scopes / areas of research under the PTC are:
CD Management
PMD Management
Loss / Power Management
Nonlinearity Management
Transmission Design Photonic NetworkThe Photonics Network group at TM R&D is in the Photonics Research Program of the Basic Research Department. The current scope of research includes:
Traffic and Network Management studies for future broadband Access and Metro Optical Networks.
Routing Algorithms and Node Architecture studies (routing methods, OXC & OADM architectures)
Hardware realization of network sub-systems for optical networks
Network Design and performance analysis Photonic DevicesThe Photonics Devices group at TM R&D is in the Photonics Research Program of the Basic Research Department. The current scope of research includes:

1. Modelling and designing Planar Lightwave Circuit (PLC) components such as splitter, directional coupler and multimode interferometer. All this passive photonic devices is a main component in photonic network.
2. Work on the fundamentals of fabrication technologies includes fabrication of PLC components using Plasma Enhanced Chemical Vapor Deposition (PECVD).
3. Studies on passive alignment between fiber array and PLC chips to achieve low loss, reliable and compact PLC component.
4. Studies on epoxy attachment between fiber array and PLC chip to achieve Telcordia standard.
5. Develop testing procedure according to Telcordia standard.
6. Studies on new photonic materials such as Photonic Crystals in order to design small and compact PLC components.
