전시품 개요

InGaAs SPAD for Quantum Cryptography (WSSPM)

WSPAD는 1550nm 파장의 단일 광자 신호를 검출하는 소자로 InGaAs를 흡수층으로 사용하며, 단일 광자 흡수에 의해 발생한 캐리어를 수백 만 배 증폭할 수 있어서 단일 광자 신호를 감지할 수 있으며, 단일광자를 신호로 사용하는 양자 키 분배(QKD) 네트워크의 수신기, 또는 초장거리 거리측정기(LRF)의 수신기로 사용된다. WSPAD는 세계 최고 수준의 매우 낮은 암계수(Dark Count) 잡음, 높은 검출 효율, 양호한 애프터 펄스 확률(APP)을 보이고 있다.

이 제품의 패키지 유형은 두 가지가 있다.
미니플랫타입(WSPAD-M)은 TO-8(WSPAD-C)에 비해 표면 실장 및 방열 능력이 우수한 장점이 있다.
InGaAs Quadrant PD (WQPD)

대면적을 갖는 InGaAs QPD는 4개의 고감도 수광 영역으로 구성되어 미사일과 같은 유도무기의 레이저 표적 탐지에 사용된다.

WQPD는 수신 영역 간의 누화(Crosstalk)를 최소화한 제품으로 900~1700nm 파장대의 넓은 스펙트럼 영역에서 동작이 가능하고 다양한 분야의 위치 센서로 사용할 수 있다.
InGaAs APD Chip (WLAAPD)

200um과 80um 직경을 갖는 InGaAs APD는 단파장 적외선(SWIR) 파장대역의 고감도 거리측정기(LRF)의 수신기에 사용된다.
APD는 내부 전류 이득(배수)을 가지므로 PIN보다 10배 이상 민감하게 작동할 수 있다.
APD 칩에는 4가지 종류가 있다.

WLAAPD200F 및 WLAAPD80F는 전면 입사 구조의 APD이며, WLAAPD200B 및 WLAAPD80B는 후면 입사형 APD이다. 후면 입사형 APD는 광신호의 왕복 운행을 사용하기 때문에 응답도가 전면 입사형 보다 20-25% 더 높다.
또한 p-bonding pad가 없어 정전용량이 전면 입사형보다 작기 때문에 동작 속도와 감도가 전면 입사형 보다 우수하다.

Exhibits Description

InGaAs SPAD for Quantum Cryptography (WSSPM)

WSPAD is a Single Photon Avalanche Diode made of InGaAs compound semiconductor to detect 1550nm single photon. Since the SPAD chip can multiply single carrier by millions of times, it can detect a signal composed of single photon. Generally, it is used as a detector for quantum cryptography, especially known as Quantum Key Distribution (QKD) network. WSPAD shows excellent performance such as very low dark count rate (DCR) noise, high detection efficiency, good after-pulse probability (APP). There are two package types. Mini-flat type(WSPAD-M) has advantages of surface-mountable and better heat-dissipation capability compared to TO-8(WSPAD-C).
InGaAs Quadrant PD (WQPD)

QPD, a large area InGaAs photodiode was developed to improve modern combat capability in Semi-Active Laser(SAL) guidance technology in missile laser seeker. QPD’s surface has four high sensitivity light receiving area which minimizes cross-talk among the receiving areas. QPD also has wide spectral response range in the area of short wavelength infrared and possesses highly effective signal detection rate compared to Silicon based photodiode. QPDs are used in position sensor, beam alignment, beam profiling, signal tracking & stabilization in mobile space communication, and increased usage in automatic position control system for autonomous vehicles.
InGaAs APD Chip (WLAAPD)

InGaAs avalanche photodiodes(APD) having diameters of 200um and 80um are released for highly sensitive LRF receivers to detect SWIR range. Since an APD has an internal current gain(multiplication), it can be more sensitively operated than PIN by 10 times or more. There are 4-types of APD chips. WLAAPD200F and WLAAPD80F are front-illumination APDs. WLAAPD200B and WLAAPD80B is bottom-illumination APD. Since bottomillumination APD employs round-trip of light signal, the responsivity is better than front-illumination by 20-25%. Furthermore, the capacitance is smaller than the front due to absence of p-bonding pad, the operation speed and sensitivity is better than the front. The bottom-illumination APD chips are flip-chip bonded to quartz substrate. The corresponding TO cans are available.
