Role at TeraView Ltd, 2003 - to date

Since September 2003 I have worked in the Technology Development group of a Cambridge-based startup company, TeraView Ltd. I design, build and evaluate Terahertz (THz) emitters, detectors and systems for pharmaceutical, medical and security applications. Key activities have included:

• Designed, built and evaluated the world's first multi-channel THz system for the detection of concealed weapons and plastic explosives.
• Developed fibre-optic THz emitter and detector components for use in TeraView's Coating Scan product.
• Developed software and hardware to extend the functionality of TeraView's Coating Scan product to examine bilayer pharmaceutical tablets. Used by clients in R&D and manufacturing quality control.
• Built optical fibre-based TPI Probe for imaging skin cancer - subsequently used in clinical trials.

Role at Agilent Technologies, 2000 - 2003

From April 2000 to March 2003 I worked as a research and development engineer in the III-V Semiconductor Devices group at Agilent Technologies’ manufacturing site in Ipswich, UK. I was involved in the design and characterization of semiconductor lasers for opto-electronic data communications. Key activities and responsibilities included:

• Developed production test for RF performance (optical eye diagram) of 10 Gb/s directly modulated lasers, achieving a multi-million dollar saving in manufacturing costs.
• Led technology investigation to improve manufacturing tolerances of laser-to-fibre alignment by nano-scale engineering of laser's waveguide. In addition to managing this project, I designed and developed new apparatus and data acquisition software to quantify tolerances and identify the required device design.
• As principal user of Agilent's Atomic Force Microscope (AFM) I investigated the electronic structure of buried heterojunction semiconductor lasers using capacitance (SCM), resistance (SSRM) and electric field (EFM) techniques.
• Developed new production process to measure and control the quality of gratings in Distributed Feedback (DFB) lasers. Modelled the reflectivity of multi-layer thin-films to optimize the exposure of resist during photolithography.

Whilst at Agilent I attended The Physics of Laser Communications M.Sc. course at the University of Essex, UK. I also took courses in Programming in Agilent VEE (similar to LabView) and in the simulation and modelling of RF and microwave circuits using Advanced Design System (ADS) software.

Role at Hewlett-Packard, 1991 - 2000

From October 1991 to April 2000 I worked as a development engineer at Hewlett-Packard’s data storage organization in Bristol, UK. I was involved in the design of three generations of DDS-format magnetic tape drives. Activities in which I was involved included:

• Responsible for making Hewlett-Packard’s DDS-4 tape drive the fastest in the world.
• Provided technical support to the new business development team, evaluating new technologies and product ideas.
• Project management of initial stages of recording technology for DDS-4.
• Played leading role in the root-cause analysis of manufacturing problems.
• Modelled and simulated electronic circuits to optimize system design and choice of components.
• Developed new measurement techniques and processes to characterize system components and performance.

Publications

My Ph.D. dissertation may be viewed online.

• Electron Tunnelling Study of High Temperature Superconductors

Two papers were published during my Ph.D..

• Electron tunnelling spectroscopy of YBa₂Cu₃O_7-x ceramics.
  A.Edgar, C.J.Adkins and S.J. Chandler. Journal of Physics C: Solid State Physics, 1987, 20 (36), L1009.
• Point-contact tunnelling measurements of Tl-Pb-Ca-Pr-Sr-Cu-O.
  S.J.Chandler and C.J.Adkins. Superconducting Science and Technology, 1991, 4, 190.

The culture within Hewlett-Packard manufacturing divisions did not encourage the external publication of R&D work. Despite this I presented at conferences with management approval, and two of my papers were published.

• Case study: an investigation into the cause of 'error rate drift'.
  Simon Chandler, B.Tucker, P.Turner and P.Heard. Tribology International, 1998, 31, 443-9.
• Error rate drift caused by rubbing noise in ferrite read heads.
  Simon Chandler. Tribology International, 2000, 33, 401-8.

I was also author of the patents

• Calibrating write pre-equalization in a data storage device. EP0959470
• Double pulse write driver. EP0959469, US6307692
• Pre-emphasis for electro-absorbtion modulator. Filing date July 2003

Whilst at Agilent Technologies I have been co-author of one paper,

• Wide temperature (−20°C - 95°C) operation of an uncooled 2.5 Gb/s 1300 nm DFB laser.
  M.Silver, W.E.Booij, S.Malik, A.Galbraith, S.Uppal, P.F.McBrien, G.M.Berry, P.D.Ryder, S.J.Chandler, D.M.Atkin, S.Chan, R.Harding, and R.M.Ash. IEEE Photonics Technology Letters, 2002, 14, 741-3. (also LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society. Cat. No. 01CH37242, 2, 796, 2001)

After teaching myself hyper-text mark-up language (HTML) I started using Hewlett-Packard's intranet to publish internal reports, thus making my work easily accessible to international colleagues. I successfully encouraged adoption of this method of organizing and distributing documentation by the R&D departments at Hewlett-Packard and Agilent Technologies.

Hobbies and Interests

I am a member of the Institute of Physics and served on the committee of the Tribology Group from 1995 to 2000. In December 1997 I played a key role in organizing the first ever three-day international conference on the Tribology of Information Storage Devices. This was extremely successful, so was repeated in December 1999 and has now become a regular bi-annual event. The proceedings of TISD’99 were published in the journal Tribology International (volume 33, issues 5, 6, 9), of which I was the guest editor.

I am webmaster for the Ipswich Mountaineering Club, and for the Information Technology, Electronics and Computing (ITEC) Group of the Institute of Physics.

I have been a keen rock climber since 1989 and, despite moving to the flat lands of Suffolk in April 2000, have just completed my most active and successful climbing season. I am gradually improving at orienteering.
