규, 소광섭( 서울대)
Nanoparticles were injected into a Bonghan
corpuscle and we observed them to flow
along the Bonghan duct on the surface of
mammalian internal organs. Another application
was injecting them into lymph nodes
so that Bonghan ducts inside lymphatic
vessels were detected and visualized by the
fluorescence of nanoparticles. Light microscope
and electron microscope images revealed
the nanoparticles captured in the extra
cellular matrix of Bonghan ducts.

F2C-3 레이저를 이용한 단일 생체 분자의 관
측및제어
홍성철( 서울대)
Single-molecule spectroscopy is a powerful
tool for studying dynamics of biomolecules.
Using its superior spatial and temporal
resolution under biologically relevant conditions,
scientists have determined the detailed
kinetics and mechanisms of a variety of
biological processes. I will review the recent
progress of single-molecule techniques,
including single-molecule FRET, optical
tweezers and magnetic tweezers.

F2D-1 광전송망에서의 PMD변화와 광성능
감시
한기호( 공주대), 이왕주(ETRI)
As bit rate per channel increases up to 40
Gb/s or beyond, PMD is gradually becoming
a main factor limiting performance of optical
transmission system. PMD characteristics
and its influence on performance of optical
signal-to-noise ratio monitoring in WDM
optical network and method to reduce the
PMD effect were theoretically and experimentally
investigated.

We present the fabrication of a single and
double core holey fiber optical cord with
bending insensitive holey fibers. The attenuation
losses at 1,383nm and 1,550nm
were measured to be 0.365dB/km and 0.258
dB/km respectively. The insertion loss with
a connector was as low as 0.1 dB. The
proposed cords show excellent properties
in terms of bending loss, compared with
conventional bending resistant SMFs at the
bending diameters of Ø5.5mm and Ø15mm.

We report the fabrication of a tunable
erbium-doped fiber ring laser with a widely
tunable ranges and excellent stability in the
C- &L-band regions. In addition, we performed
two experiments for application of
tunable fiber ring laser. The applications are
measuring system for coefficient of linear
thermal expansion (CTE) of ULE and spectroscopy
of acetylene (13C2H2) and hydrogen
cyanide (H13C14N).

We have fabricated a broadband long period
grating (LPG) on hollow optical fiber (HOF)
by using femtosecond laser pulses. The
filter showed a low insertion loss of 1.7 dB
and very broad FWHM of 160 nm.

정용덕, 최광성, 심재식, 유현규, 김제하(ETRI)
We developed an analog optical systemon-package
(SoP) transmitter for 60 GHz
band radio-over-fiber (RoF) link. The SoP
transmitter consisted of an electroabsorption
modulator, RF amplifiers, and a band
pass filter. 60 GHz RoF wireless link was
prepared to measure the performance of the
SoP transmitter. The transmission characteristics
of 64 quadrature amplitude modulation
(QAM) data of 60 GHz RoF wireless
link including SoP transmitter were investigated
by measuring the error vector
magnitude (EVM) and signal-to-noise ratio
(SNR) with a base band frequency.

F3A-2 Enhancement of the internal quantum
efficiency of Light Emitting Diodes by
Surface-Plasmon Resonant Gratings

Kim, Jin-Ha Kim(Samsung Electromechanics)
We characterized the enhancement efficiency
of spontaneous emission rates in a surfaceplasmon
enhanced light-emitting diode with
a plasmonic (or metallic) grating. We numerically
evaluated the Purcell enhancement
factor of surface-plasmon enhanced LEDs
by the finite different time domain method
including Green’s function calculation. We
found that a reflection-type of the surfaceplasmon
resonant gratings could enhance
the internal quantum efficiency of a conventional
GaN LED dramatically.

We have analyzed the transmitter characteristics
of 850 nm oxide¬ VCSELs (Vertical–
Cavity Surface–

operation is just below the threshold current.

The effect of fiber dispersion on signal
distribution according to a modulation schemes
investigated by using a novel heterodyne
electro-optic modulator which enabled both
double sideband(DSB) and single sideband
(SSB) modulation. It was confirmed that
transmission characteristics of SSB modulation
were superior to DSB's. The experiment
results showed that Signal-to-Noise Ratio
(SNR) was better than 20dB at 10km
long
fiber-optic transmission.
