BATOP不僅提供單帶隙天線，還包括整合了微透鏡的高能大狹縫交叉光電導天線陣列 IPCA和整套的太赫茲光譜儀。
光電導天線陣列 IPCA產(chǎn)品特點：
• 高太赫茲輸出功率（zui高可至280uW）
• 大面積發(fā)射/探測
• 高的轉(zhuǎn)換效率~ 10-4（100µW THz / 1 W optical power）
• 譜寬 0.1 – 3 THz
• 封裝有超半球Si透鏡和SiO2透鏡陣列
光電導天線陣列 IPCA工作原理
An extended gap along the finger electrodes of the iPCA is illuminated by a short pulse laser beam. By using the microlens array only every second gap between the finger structure is excited by the laser. The fill factor of the lens array of 73.5 % ensures, that nearly the total optical laser energy is used for excitation of carriers. Despite of the large emitting area the needed voltage for the carrier excitation is low (< 35 V) because of the small gap of only 5 µm. The coherent excitation of the single emitters located at every microlens spot results in a constructive interference of the radiated THz waves in the far field.
封裝:
iPCA chip, size 4 mm x 4 mm, thickness 625µm, mounted on 25.4 mm diameter black aluminium mount with prealigned hyperhemispherical silicon lens ∅ 12 mm and prealigned fused silica lens array, size 2 mm x 2 mm, and 1 m coaxial cable (RG 178) with BNC or SMA connector.
