Performance of surface-plasma-wave fiber-optic polarizers.

Area of Science:

• Optoelectronics
• Materials Science
• Fiber Optics

Background:

• Surface-plasma-wave (SPW) fiber-optic polarizers are crucial optical components.
• Their performance is sensitive to fabrication parameters.
• Understanding these sensitivities is key for device optimization.

Purpose of the Study:

• To investigate the impact of polishing depth on SPW fiber-optic polarizers.
• To analyze the influence of metal film thickness on polarizer performance.
• To isolate and quantify the effects of these two critical fabrication parameters.

Main Methods:

• Fabrication of fiber-optic polarizers with controlled variations in polishing depth.
• Fabrication of polarizers with precisely controlled metal film thicknesses.
• Experimental isolation and separate analysis of the effects of polishing depth and film thickness on TM-like polarization transmission and polarization extinction ratio.

Main Results:

• Polishing depth variations were found to significantly alter TM-like polarization transmission characteristics.
• Metal film thickness variations demonstrated a notable impact on the polarization extinction ratio.
• The study successfully isolated and quantified the independent contributions of polishing depth and film thickness.

Conclusions:

• Both polishing depth and metal film thickness are critical parameters influencing the performance of SPW fiber-optic polarizers.
• Precise control over these fabrication variables is essential for achieving desired polarization characteristics.
• This research provides valuable insights for the design and manufacturing of high-performance fiber-optic polarizers.
