    • This disclosure concerns optical packages such as may be used in optical transceivers and transmitters. In one example, an optical package includes a header assembly having a base portion to which is attached a header structure that is split into first and second portions that are separated from each other by a space. The header structure further includes one or more electrical leads extending through the base portion and into one of the first and second portions of the header structure. An active temperature control device is included in the optical package and resides in the space between the first and second portions of the header structure. Finally, an optical element, such as a laser, is provided that is arranged for thermal communication with the active temperature control device so that operation of the optical element can be controlled by way of the active temperature control device.

    • A ferroelectric liquid crystal-based light valve comprising a light input, a light output, a polarizing beam splitter, a reflective spatial light modulator and a switchable half-wave plate. Light polarized parallel to a first direction is received through the light input. Light from the light input and reflected by the spatial light modulator is output from the light output. The reflective spatial light modulator is structured as a quarter-wave plate and has a principal axis that switches through an angle &phgr;. The polarizing beam splitter has orthogonal directions of maximum transmissivity and maximum reflectivity, one of which is parallel to the first direction. The polarizing beam splitter is located and aligned relative to the light input, the light output, and the spatial light modulator to transmit or reflect the light from the light input towards the spatial light modulator, and to reflect or transmit, respectively, towards the light output the light reflected by the spatial light modulator and having a direction of polarization substantially orthogonal to the first direction. The switchable half-wave plate is located between the beam splitter and the spatial light modulator, is structured as a half-wave plate and has a principal axis that switches through an angle &thgr;, substantially equal to &phgr;/2. The switchable half-wave plate inverts the sense of the light valve during the balance period of each display period to enable the light valve to generate a positive image, and therefore be illuminated, during the balance period in addition to during the illumination period.
    • 一种铁电液晶型光阀,包括光输入,光输出,偏振分束器,反射空间光调制器和可切换半波片。 平行于第一方向的偏振光通过光输入被接收。 来自光输入并由空间光调制器反射的光从光输出输出。 反射空间光调制器被构造为四分之一波片,并且具有通过角度phi切换的主轴。 偏振分束器具有最大透射率和最大反射率的正交方向,其中一个平行于第一方向。 偏振分束器相对于光输入,光输出和空间光调制器被定位和对准,以将来自光输入的光透射或反射到空间光调制器,并且分别反射或发射到光 输出由空间光调制器反射并具有基本上与第一方向正交的偏振方向的光。 可切换半波片位于分束器和空间光调制器之间,被构造为半波片,并且具有切换基本等于phi / 2的角度θ的主轴。 可切换半波片在每个显示周期的平衡期间反转光阀的感测,以使光阀产生正像,并且因此在平衡期间除了在照明周期之外也被照亮。
