本文报道了在表面声子极化激元（SPPs）能量增强的影响下，微结构玻璃管表面温度的测量。玻璃管被设计成引导单色热能以改善热传导或用作辐射源。模拟结果表明，当波导半径在2.0 ~ 10 μm之间时，自由程有很强的增强。在高吸收率的波导区域上吸收增强的SPP能量有可能引起局部温度升高。各种形状的微型玻璃管的简单制造，并通过使用铂丝在真空室中加热。利用红外数字热显微镜和微型热电偶测量了玻璃管的表面温度，研究了锥形和细玻璃管的温度分布。
We report a temperature measurement of the surface of micro structured glass tube, affected by surface phonon polaritons'(SPPs) energy enhancement. The glass tubes were designed to guide monochromatic thermal energy to improve heat conduction or serve as radiative source. The simulation results show strong enhancement of the Free Path when a wave guide radius is between 2.0 and 10 μm. Absorption of enhanced SPPs energy on the waveguide areas with high absorptivity has some possibility to cause local rise in temperature. Various shapes of micro glass tubes are simply fabricated, and heated by using a Pt wire in a vacuum chamber. Surface temperatures of glass tubes are measured by infrared digital thermo microscope as well as by using a micro-thermocouple to investigate the temperature distribution on both tapered and thin micro glass tubes.
