moderate penalties compared to a standard
50GHz-grid.

8:30 AM - 10:00 AM
Session TuF: Vertical-Cavity Surface
Emitting Lasers II
Session Chair: Alexei Sirbu, École
Polytechnique Fédérale de Lausanne, Lausanne,
Switzerland
TuF1 8:30 AM - 8:45 AM
Beam Steering Modulation with Phased
Vertical Cavity Laser Arrays, M. Johnson,
University of Illinois at Urbana-Champaign,
Urbana, IL, USA, D. F. Siriani, MIT Lincoln
Laboratories, Lexington, MA, USA, and
K. D. Choquette, University of Illinois at Urbana-
Champaign, Urbana, IL, USA
Beam steering with phased vertical cavity laser
arrays is demonstrated at equipment-limited
rates up to 100 MHz. The dominant phaseshifting
mechanism is found to shift from
thermal to carrier-induced effects with increasing
modulation speed.

On-Chip Electro-Thermal Beam Steering
based on Slow-light Bragg Reflector
Waveguide Laterally Integrated with
VCSEL, T. Shimada, A. Matsutani and
F. Koyama, Tokyo Institute of Technology,
Yokohama, Kanagawa, Japan
We demonstrate on-chip beam steering based on
a slow-light Bragg reflector waveguide laterally
integrated with VCSEL. Electro-thermal tuning of
the slow-light waveguide enables continuous
beam steering over 9° with a diffraction-limited
divergence angle of 2.2°

Frequency Dependent Polarization

Emitting Lasers with Electrical Injection,
A. V. Barve, Y. Zheng, L. A. Johansson and
L. A. Coldren, University of California - Santa
Barbara, Santa Barbara, CA, USA
We report on the polarization dynamics in
VCSELs with a small frequency modulation. The
polarization state of a VCSEL is shown to be
controlled by only changing the frequency of the
modulation to electrical injection.

F. Koyama, Tokyo Institute of Technology,
Yokohama, Kanagawa, Japan
We demonstrate the athermal operation and the
wavelength tuning of 850nm-GaAs-VCSELs
using thermally actuated MEMS structure at the
same time. A small temperature dependence of -
0.011 nm/K and wavelength tuning of 4 nm was
obtained.

A. Arbabi and L. L. Goddard, University of Illinois
at Urbana-Champaign, Urbana, IL, USA
We present a method for accurate determination
of refractive indices of waveguide core and
cladding layers using reflective microrings. The
resonant mode azimuthal order ambiguity is
resolved by introducing a grating on the
microrings.

in air. A cell-counting approach describes its
periodic evolution with interesting interplays
among edge, surface and bulk states.
