设计了一种新型的可拆卸光器件，用于将单模波导与多光纤阵列进行无源对准耦合。该器件是通过在波导芯片上形成v型凹槽并精确地对芯片的两端部分进行成型而制成的。1/spl times/8耦合装置具有10.7 dB的低插入损耗和100次重新连接时/spl plusmn/0.2 dB的小损耗变化。
A novel demountable optical device is developed for coupling single-mode waveguides to a multifiber array using passive alignment. This device is fabricated by forming V-grooves on a waveguide chip and precisely molding both end portions of the chip. The 1/spl times/8 coupling device exhibits a low insertion loss of 10.7 dB and a small loss change of /spl plusmn/0.2 dB for 100 reconnections.
