"该研究探讨了膜的相容性如何影响染料掺杂的聚合物DR1 / SU-8的电光性能。研究者通过在硅基板上制作由DR1 / SU-8核心和不同材料（如NOA73、SU-8、PDMS或PMMA）作为上覆层的多层膜，来研究被动包覆材料与DR1 / SU-8之间的相容性。他们特别关注了界面形态、电场极化、以及这些膜的电光信号响应。"
文章指出，通过使用过量的紫外线照射和高温处理，可以实现DR1 / SU-8核心与NOA73上覆层之间的良好化学结合，避免腐蚀和分层。利用原子力显微镜(AFM)测量上包层表面的粗糙度，确认了极化过程的有效性。极化后的电光(EO)信号响应被用来评估DR1发色团的取向，这通过Teng-Man方法得以实现。此外，研究还测量了包层的电阻率以解释电光响应的差异。
在极化过程中，发现延长冷却时间可以优化NOA73 / (DR1 / SU-8)构型的电光性能，并在550小时内达到最佳的幅度稳定性。同时，通过构建通道波导，研究人员考察了极化对光损耗的影响，强调了选择具有优异电学和化学性能的被动包覆层对于构建染料-聚合物系统中的光学非线性的重要性。
关键词包括"电光聚合物"、"相容性"、"被动包覆"和"波导"，这表明研究的重点在于理解材料的相互作用如何影响电光性能，特别是在制造光学器件如波导时的潜在应用。这些发现对于未来设计和优化基于聚合物的电光器件，特别是那些利用染料掺杂技术的器件，具有重要的指导意义。通过改进材料的相容性和极化过程，可以实现更高效、稳定的电光性能，从而推动光学通信、光电子学和其他相关领域的技术进步。

The

was
measured
at

of

to
explain
the

The

the

and

to

Introduction
Electro-optic
(EO)
polymers
are
prospective
materials
with
many
favorable
merits
for
various
applications,
including
opti-
cal
network
components,
on-chip
optical
interconnects
[1–3],
microwave
photonics
and
others
[4–6].
They
have
specialties
of
large
EO
coefficients,
low
optical
loss
at
1.30
and
1.55
m
telecom-
munication
wavelengths,
low
dispersion
of
refractive
index
(RI)
between
optical
frequencies
and
millimeter
waves,
easy
to
pro-
cess
and
relatively
low
cost.
Nonlinear
polymers
and
chromophores
with
high
molecular
polarizability
have
been
designed,
tailored
and
introduced
from
molecular
engineering
both
theoretically
and
synthetically
[7–9].
However,
most
of
these
materials
are
not
com-
mercially
available
yet.
Consequently,
these
excellent
outcomes
of
molecular
engineering
are
incapable
of
playing
desirable
roles

Among
nonlinear
optical
systems,
guest–host
polymers
need
no
chem-
ical
attachment
of
chromophores
to
the
host
polymer
and
can
be
synthesized
at
a
lower
cost
than
any
other
systems,
including
side-chain,
cross-linked,
and
main-chain
polymers
that
are
syn-
thesized
with
more
complicated
reaction
[10–12].
Recently,
we
have
demonstrated
the
approach
to
overcome
disadvantages
of

Practical
optical
waveguide
devices
require
the
active
layer
to
be
sandwiched
between
two
cladding
layers
[14].
For
EO
wave-
guide,
compatible
buffer
and
cladding
layers
are
necessary
for
light
guiding
in
the
active
core.
These
claddings
commonly
have
char-
acteristics
of
similar
thickness
with
the
active
layer,
relatively
low
optical
loss,
and
appropriate
RI
supporting
mode
propagation
[15].
Another
essential
request
for
the
sandwiched
layers
is
to
build
an
effective
poling
field

the
multilayer
geometry
