본 명세서에는 생물학적 또는 화학적 물질을 지지하도록 설정된 검출기 표면을 정의하는 구조체 및 광 센서에 의해 검출된 광자를 사용하여 데이터 신호를 전송하는 회로부과 광 센서를 포함하는 센서 어레이를 포함하는 디바이스가 제공된다. 디바이스는 센서 어레이의 검출 대역에서 형광 범위 잡음을 감소시키기 위한 하나 이상의 피처들을 포함할 수 있다. A device comprising: a structure (260) defining a detector surface (206) for supporting biological or chemical samples; a sensor array (201) comprising light sensors (202), and circuitry to transmit data signals based on photons detected by the light sensors (202); and a guide array comprising light guides (214); wherein light guides (214) of the guide array receive excitation light (101) andemissions signal light (501) from the detector surface (206), wherein the light guides (214) extend toward respective light sensors (202) of the sensor array (201) and comprise filter material that blocks the excitation light and permits the emissions signal light to propagate toward the respective light sensors (202), wherein the detector surface (206) includes a reaction recess (210), the reaction recess comprising an index of refraction and a dimension sufficient to cancel background light energy incident on the detector surface in a detection band of the sensor array. A method comprising steps for fabricating the device.
