Cambridge Graphene Centre

Research Centre on Graphene, Layered Crystals and Hybrid Nanomaterials
 

Our Photonics and Optoelectronics lab is made up of four bays, broken up by specialised fields. These bays are separated with metal safety curtains to prevent any light contamination, and each has two floating, vibration-resistant tables from Thorlabs.

Below are examples of experiments currently being run in each bay, but it is by no means an exhaustive list of what is possible with our equipment.

For training on any of the equipment, please contact the Lab Leader, Dr Jing He or their deputy, Ms Yijia Zheng, for the listed equipment.

The booking system can be found here.

Bay 1

Principal User: Mr Sohail Abbas
Deputy User: Dr Chao Wen

Optoelectronics

Optoelectronics is the study of how light affects electronic devices, in ways such as photoresistors or photovoltaic cells (solar cells).

Some of the equipment they use includes;
Power Meters,
SMU (source Meter Units),
Multimeters,
Photocurrent mapping.

 

 

Bay 2

Principal User: Ms Yijia Zheng
Deputy User: Dr Jing He
 

Optical Characterisation

A Z-scan has been designed for the optical Characterisation of graphene and other 2D materials.

Ultrafast Optical Spectroscopy

The other half of this bay is designated for Ultrafast spectroscopy, powered by a Chameleon Compact OPO Ti: Sapphire Laser and an APR pulseSelect Dual.

 

Bay 3

Principal User: Dr Jing HeDr Chao Wen
Deputy User: Ms Yijia Zheng

Solid State Lasers

These are mode-locked, solid-state lasers made from graphene.

Student Training Laser

We have a simplified gas laser, which is used to teach our students all the basic principles of photonics.

 

Bay 4

Principal User: Dr Jing He
Deputy User: Ms Yijia Zheng

 

Fiber Lasers

These are mode-locked, Fiber lasers made from graphene.
