The University of Nottingham
Malaysia Campus is developing new
technologies for high-speed optical
fiber communication systems to
overcome cost and performance
limitation of existing techniques.
A team of researchers from the Faculty
of Engineering at the University of
Nottingham Malaysia Campus, led
by Dr Amin Malek Mohammadi,
have designed and developed a new
multiplexing technique that requires
only one modulator for any number
of users, which will reduce the cost
Fiber optics is one of the most
essential aspects of modern
communications. Data transmission
using optical fiber is very efficient
over long distances (up to thousands
of kilometers), and a single fiber
can carry multiple data streams
represented by different wavelengths
(color) of light simultaneously.
However, there are some bottlenecks
on the information superhighway.
Early optical fibre technologies
encoded data as “wiggles” within a
single channel but in recent years a
number of other methods have been
used to transmit the information
(either voice or data) from more
than one source to more than one
destination on the same transmission
medium much as a large water pipe
can carry water to several separate
houses at once.
Wavelength division multiplexing
(WDM), for example, uses a number
of lasers to encode strings of data on
different colours of light then sends
them through one fibre together.
“The major disadvantage of WDM
is the spectral inefficiency because
of large number of wavelengths
required. The use of different
wavelengths requires different light
sources and photo detectors thus
adding to the cost of the system,” said
Dr Amin Malek Mohammadi, head
of Electrical, Electronic and Applied
Mathematics Research division.
The proposed multiplexing technique
has smaller spectral width; therefore
it leads towards better spectral
efficiency and dispersion tolerance
in comparison to existing techniques
such as TDM and WDM. This novel
technique supports many users
per wavelength (WDM channel).
Consequently, the capacity utilization
of the WDM channels can be
increased tremendously.
“Our research findings have already
been presented in international
conferences and published in major
international journals in the area of
telecommunications,” said Dr Amin
Malek Mohammadi.
The team have already proved the
concept of their technology and are
now negotiating with industry to trial
their product.
With funding from The University of
Nottingham, Ministry of Science and
Innovation of Malaysia, and private
sector organizations in the country,
the UNMC photonic laboratory is
working with other universities across
the world to design and develop
new technologies in the area of

Inaugurated in October 2013 with
14 students from the Executive Post
Graduate Program in Management
(EPGP), IIM Bangalore launched its
mentoring initiative called “Shikshu”
on a much bigger scale in September
2014, targeting the entire EPGP Class of
2014/15 with a batch size of 58.
“Shikshu”, which means apprentice
in Sanskrit, gives EPGP students the
rare opportunity of experiencing
first-hand how a CEO’s office works.
“It is unique because it ensures
that EPGP student and IIMB alumni
participants are matched based on
commonalities in their personal and
professional profiles,” says Professor
G Shainesh, Chair of Executive Post
Graduate Program in Management, IIM
The engagement initiative has several
of IIMB’s alumni, who work at the
top echelons of various reputed
organizations, mentor the EPGP
students, who spend a day at the
offices of the alumni, attend meetings
and interact with senior executives at
these offices. It connects EPGP students,
for one full day, with alumni mentors
who are willing to provide advice on
career exploration on how to bridge
the gap from student life to work life.
The mentors remain in touch with
the students after the project to set
The engagement initiative uses job-
specific situations as the practice fields
and rehearsal halls for learning complex
skills. “The student has an opportunity
to talk with his/her mentor, develop
work scenarios that are effective
and productive, and seek feedback
about improving his/her skills and
knowledge,” Shainesh adds.
“I must state that Shikshu is a
wonderful initiative. In fact, I wish it
were there when I was a student at
IIMB,” exclaims Bhargav Dasgupta, an
alumnus of IIMB’s batch of 1992 and
CEO, ICICI Lombard.
“I got first-hand experience of IBM—
its mission, culture, organizational
structure, and operational style. I got
a peek into the opportunities and
challenges of doing business in India
Connect with a mentor,
prepare for the real world
and how a business leader plans for the
future. This is a rare opportunity and
a connection that I will leverage in the
future,” says Sandeepan Sarkar, who
shadowed Amit Sharma, vice president
and general manager – operations, IBM
India/South Asia.
Rakesh Godhwani, head of Alumni
Office at IIM Bangalore, says “The
Shikshu program is a wonderful
initiative to engage our alumni and
use their rich experience in helping the
students learn beyond the classroom.
“To be able to shadow a CEO for a day,
see how she/he operates and captains
the company could be transformational
for students and hopefully turn them
into better leaders of tomorrow. The
alumni of IIMB have been a pillar of the
institute, and the Shikshu program is
a great example of how they can add
value to the EPGP program.”
