Abstract

본 발명은 광 통신 분야에서 광 섬유간의 접속과 광 섬유와 광원간의 접속 등에 집광용으로 사용되는 집광용 고분자 GRIN(GRadient INdex) 렌즈를 제조하는 방법에 관한 것이다.
본 발명의 고분자 GRIN 렌즈의 제작방법은 황화에 의해 폴리스티렌의 굴절률 값이 감소하는 특성을 이용한 것으로, 스티렌(styrene)과 같이 황화(sulfonation)가 가능한 반향성 단량첼르 가교제(cross－linking agent) 및 중합 개시제와 함께 구형 또는 봉의 형태로 중합하는 공정, 소정의 용제(solvent)를 이용하여 상기 중합된 가교 고분자를 팽창시키는 공정, 및 상기 팽창된 가교 고분자를 황산으로 황화시키는 공정으로 구성된다.
본 발명에 의하면, 황화시의 황산의 확산에 의해 굴절률 분포가 결정되기 때문에 굴절률 분포의 제어가 용이하다.

Claims (2)

  1. 황화가 가능하면서 수소성(hydrophobicity)을 지닌 방향성 단량체(aromatic monomer)를 가교제(cross－linking agent) 및 중합개시제(initiator)와 함께 혼합한 다음, 현탁 중합(suspension polymerization)시켜 구형의 가교고분자(cross－linked polymer)를 형성하는 공정; 상기 가교고분자를 소정의 용제(solvent)를 이용하여 팽창(swelling)시키는 공정; 및 상기 공정을 통하여 팽창된 가교고분자를 소정 온도로 가온된 황산 용액을 이용하여 구의 중심부에서 굴절률이 가장 높고 중심에서 멀어질수록 점차적으로 감소하는 굴절률 분포를 갖도록 황화(sulfonation)시키는 공정으로 이루어진 구형의 고분자 GRIN 렌즈의 제조방법.
  2. 황화가 가능하면서 수소성(hydrophobicity) 및 친수성(hydrophilicity)을 띤 방향성 단량체(aromatic monomer)를 방향성 가교제(cross－linking agent) 및 중합개시제(initiator)와 함께 혼합한 후, 이 혼합물을 튜브에 넣고 중합시켜 봉상(rod)의 가교고분자(cross－linked polymer)를 형성하는 공정; 상기 튜브를 제거한 후, 중합된 가교고분자를 소정의 용제(solvent)를 이용하여 팽창(swelling)시키는 공정; 및 상기 공정을 통하여 팽창된 가교고분자를 소정 온도로 가열된 황산을 이용하여 봉의 중심부에서 굴절률이 가장 높고 중심에서 멀어질수록 점차적으로 감소하는 굴절률 분포를 갖도록 황화(sulfonation)시키는 공정으로 이루어진 봉상의 고분자 GRIN 렌즈의 제조방법.
