野田 進(Noda Susumu) 한국비교노동법학회 2018 노동법논총 Vol.43 No.-
일본의 노동법 규범 시스템상 노동조건은 노동입법 → 단체협약 → 취업규칙 → 근로계약이라는 규범의 계층 구조로 결정되고, 후순위에 의한 근로조건 기준은 이전 순위 그것을 하회할 수 없는 구조로 설명된다. 문제는 단체협약 체결율이 저조하여, 사용자의 일방적인 단독결정에 따라 근로조건이 결정될 수 있는 취업규칙으로 근로조건 기준이 설정되는 효과가 문제될 수 있다. 노동법 본연의 목적으로 노사의 단체협상을 통해 단체협약 체결이 바람직하나, 현실의 괴리는 너무 커 노사관계법 기능과 역할에 큰 문제가 노출되고 있다. 이러한 측면에서 프랑스의 사례는 도움을 준다. 프랑스도 노동조합 조직률은 우리와 유사한 수준에 불과하지만, 노동협약을 통한 규범체계를 활성화하기 위한 노력을 지속적으로 추진해왔으며, 특히 2016년 8월에 “노동, 사회적 대화의 현대화 및 직업행정의 안전화에 관한 2016년 8월 8일 법률, 제2016-1088호”는 노동법전의 광범위한 영역에 대해 한층 더 근본적 개혁을 가져오는 재구축을 실현한 바 있어, 이 내용을 소개하면서 우리의 노동법의 규제력의 정체상황을 타개하기 위한 시사점을 찾고자 한다.
Symmetrically glass-clad photonic crystal nanocavities with ultrahigh quality factors.
Song, Bong-Shik,Jeon, Seung-Woo,Noda, Susumu Optical Society of America 2011 Optics letters Vol.36 No.1
<P>We design and fabricate ultra-high-quality (Q) photonic nanocavities in a symmetrically glass-clad silicon (Si) two-dimensional (2D) photonic crystal (PhC) structure. We theoretically investigate the dependence of the refractive index of the glass on the Q factors for asymmetric and symmetric structures. We show that the index-symmetric distribution of the glass is a critical factor to realize ultrahigh Q factors for glass-clad 2D PhC structures. We fabricate symmetrically glass-clad Si PhC nanocavities and achieve a record Q factor of 1×10<sup>6</sup>, comparable with the highest Q factors of nanocavities in air-bridge structures.</P>

<P>We demonstrate fine tuning of the resonant wavelength of a nanocavity in a two-dimensional silicon-based photonic crystal slab structure by subnanometer control of the airhole diameter and slab thickness. Theoretical investigation shows that the resonant wavelength depends linearly on the latter two parameters. To experimentally demonstrate the fine tuning of the resonant wavelength, we control these parameters through chemical processes. The resonant-wavelength shift is tuned to 3.25 and 0.36 nm by use of two oxidizing processes. The latter shift, which corresponds to a 0.14 nm thick silicon layer, is considerably smaller than shifts achieved in previous studies.</P>
Experimental investigation of thermo-optic effects in SiC and Si photonic crystal nanocavities.
Yamada, Shota,Song, Bong-Shik,Asano, Takashi,Noda, Susumu Optical Society of America 2011 Optics letters Vol.36 No.20
<P>We experimentally investigate and compare the thermo-optic effects of silicon carbide (SiC) and silicon (Si) photonic crystal nanocavities on their resonant wavelengths over a temperature range of 25?C to nearly 200?C by using a laser source with a wavelength close to the telecommunication wavelength range of 1550?nm. The measured results clearly show that the shift in the resonant wavelength of the SiC cavity is significantly (by a factor of 3) less than that of the Si cavity for the same ambient temperature changes. In addition, the measured results provide direct estimates of the thermo-optic coefficients (dn/dT) for thin SiC and Si as 3.8710(-5)/C and 1.6010(-4)/C, respectively, for this temperature range.</P>
Measurement of optical loss in nanophotonic waveguides using integrated cavities
Jeon, Seungwoo,Kim, Heungjoon,Song, Bong-Shik,Yamaguchi, Yuki,Asano, Takashi,Noda, Susumu OPTICAL SOCIETY OF AMERICA 2016 Optics letters Vol.41 No.23
<P>Measurement of optical loss in nanophotonic waveguides is necessary for monitoring the properties of integrated photonic devices. We propose a simple method of measuring the optical loss using integrated nanocavities. It is shown theoretically that weak coupling between the waveguide and cavities leads to a direct estimation of the optical loss by measuring light radiated from the cavities. In addition, we experimentally demonstrate the optical loss in a fabricated photonic crystal waveguide. Our method gives not only a degree of freedom in real-time monitoring of the optical properties of nanophotonic structures, but it also can be used for various waveguide-based applications.

Suppression of multiple photon absorption in a SiC photonic crystal nanocavity operating at 1.55 μm.
Yamada, Shota,Song, Bong-Shik,Upham, Jeremy,Asano, Takashi,Tanaka, Yoshinori,Noda, Susumu Optical Society of America 2012 Optics express Vol.20 No.14
<P>We show that a SiC photonic crystal cannot only inhibit two photon absorption completely, but also suppress higher-order multiple photon absorption significantly at telecommunication wavelengths, compared to conventional Si-based photonic crystal nanocavities. Resonant spectra of a SiC nanocavity maintain a Lorentzian profile even at input energies 100 times higher than what can be applied to a Si nanocavity without causing nonlinear effects. Theoretical fitting of the results indicates that the four photon absorption coefficient in the SiC nanocavity is less than 2.0 10(-5) cm(5)/GW(3). These results will contribute to the development of high-power applications of SiC nanocavities such as harmonic generation, parametric down conversion, and Raman amplification.</P>
